Immigration attorney on retainer: H-1B advisory, employment-based immigration, and I-9 compliance on monthly retainer

August 6, 2026 · ~22 min read

A mid-size technology company with 340 employees receives a Notice of Inspection (NOI) from U.S. Immigration and Customs Enforcement (ICE) requiring the production of Form I-9 Employment Eligibility Verification records for all current employees and all employees who separated from employment within the three years preceding the date of the NOI. The company’s HR manager has been completing Form I-9 records since the company’s founding using a spreadsheet-based tracking system and paper I-9 forms stored in employee personnel files, without maintaining a separate I-9 binder or conducting any internal I-9 audits. The company has approximately 85 sponsored H-1B workers, 22 employees on Optional Practical Training (OPT) Employment Authorization Documents (EADs), and 12 employees on other temporary work authorization documents with expiration dates ranging from 30 days to 24 months from the NOI date.

The company engages a business immigration attorney to manage the ICE NOI response. The attorney’s rapid preliminary review of a sample of the company’s I-9 records identifies systemic violations: I-9 forms completed more than three business days after the employee’s first day of employment (a technical violation under 8 CFR §274a.2(b)(1)(ii)); Section 2 document verification completed by an employee who was not designated to complete Section 2 (a procedural violation); I-9 forms for employees whose temporary employment authorization has expired with no reverification completed in Section 3 (a substantive violation for the post-expiration period of employment); and missing I-9 forms for three employees hired within the past year. The attorney advises that the ICE inspection period (during which ICE provides a minimum of three business days to produce I-9 records under 8 CFR §274a.2(b)(2)(ii)) is insufficient to conduct a full I-9 audit and implement corrections without a corrective action plan, and recommends requesting a two-week extension from the ICE special agent in charge to allow the company to conduct an internal audit, complete correctable technical violations under the employer’s guidance on correction (single-line strikethroughs, corrections initialed and dated), and prepare a memorandum documenting the company’s good-faith compliance efforts.

Business immigration attorneys and corporate immigration counsel on monthly retainer — J.D.s specializing in employment-based immigration, nonimmigrant visa petitions, and employer immigration compliance — do a substantial share of their highest-value advisory work between USCIS filings, PERM certifications, and ICE inspections. This guide covers employment-based immigration advisory and immigration compliance: the legal frameworks behind each service area, the applicable INA provisions, CFR regulations, and USCIS policies that govern the advisory, and how to structure a retainer agreement that makes the ongoing immigration advisory work visible between filing and enforcement milestones.

Employment-based immigration advisory

Employment-based immigration advisory is the retainer function that manages the employer’s sponsorship obligations and strategy across the full spectrum of nonimmigrant work visas (H-1B, O-1A, L-1A, L-1B, TN, E-3) and employment-based immigrant petition categories (EB-1A, EB-1C, EB-2 NIW, EB-3 via PERM labor certification). The retained business immigration attorney monitors the employer’s sponsored employee visa status portfolio, advises on the immigration implications of workforce changes and international expansion, and coordinates the filing strategy for cap-subject visa petitions and employment-based immigrant petitions with priority date movements in the DOS Visa Bulletin.

H-1B specialty occupation advisory and LCA prevailing wage determination

The H-1B nonimmigrant visa category under INA §101(a)(15)(H)(i)(b) allows U.S. employers to temporarily employ foreign nationals in specialty occupations — occupations that require the theoretical and practical application of a body of highly specialized knowledge and the attainment of a bachelor’s or higher degree in the specific specialty (or its equivalent) as a minimum for entry into the occupation in the United States. The H-1B category is subject to an annual numerical cap of 65,000 new cap-subject H-1B visas per fiscal year, plus an additional 20,000 visas reserved for beneficiaries who hold a U.S. master’s degree or higher (the “master’s cap” or “U.S. advanced degree exemption”), allocated through an annual electronic registration lottery.

H-1B cap registration lottery strategy requires the retained business immigration attorney to evaluate each candidate and position the employer is considering for H-1B cap registration during the USCIS electronic registration window (typically March 1-20 of the year preceding the October 1 fiscal year start date). The specialty occupation analysis under 8 CFR §214.2(h)(4)(ii) evaluates whether the position satisfies at least one of four alternative criteria: (1) a baccalaureate or higher degree or its equivalent is normally the minimum requirement for entry into the particular position; (2) the degree requirement is common to the industry in parallel positions among similar organizations; (3) the employer normally requires a degree or its equivalent for the position; or (4) the nature of the specific duties is so specialized and complex that the knowledge required to perform the duties is usually associated with the attainment of a baccalaureate or higher degree. For positions with high H-1B Request for Evidence (RFE) and denial rates in recent USCIS adjudication data (IT consulting, accounting, HR, marketing, management analyst), the attorney evaluates whether the position description can be strengthened to more clearly satisfy the specialty occupation criteria, and whether alternative visa categories (O-1A, TN for Canadian and Mexican nationals, E-3 for Australian nationals) are available for candidates not selected in the H-1B lottery.

Labor Condition Application (LCA) prevailing wage determination under 20 CFR Part 655, Subpart H is the DOL component of every H-1B petition filing. The employer must file an LCA with the Department of Labor through the FLAG system attesting that: (1) the employer will pay the H-1B worker at least the required wage (the higher of the prevailing wage for the occupational classification in the geographic area of employment, determined by reference to the DOL OES wage survey or an acceptable private wage survey, and the actual wage paid to similarly employed workers at the worksite); (2) the employment of the H-1B worker will not adversely affect the working conditions of similarly employed U.S. workers; (3) there is no strike, lockout, or work stoppage in the occupation at the employer’s worksite; and (4) the employer has provided notice of the LCA filing to its U.S. workers in the H-1B occupation through either electronic or physical posting at the worksite. The retained attorney advising on LCA prevailing wage determination evaluates whether the DOL OES prevailing wage for the SOC code and geographic area matches the employer’s compensation structure for the position (a prevailing wage above the employer’s actual wage structure signals a risk that the H-1B worker will be underpaid relative to the required wage), advises on whether an alternative prevailing wage source (a SESA private survey or a recognized private wage survey) produces a more favorable prevailing wage determination, and advises on the LCA posting requirements including the timing and location of the worksite notice.

O-1A extraordinary ability petition advisory

The O-1A nonimmigrant visa category under INA §101(a)(15)(O)(i) is available to individuals who have demonstrated extraordinary ability in the sciences, education, business, or athletics — defined as a level of expertise indicating that the person is one of the small percentage who have risen to the very top of the field of endeavor. Unlike the H-1B category, the O-1A category is not subject to a numerical cap, is not dependent on an employer-filed LCA, and is available to beneficiaries in any field of the sciences, education, or business (not limited to specialty occupations requiring a specific degree). The O-1A category is increasingly used as an alternative to the H-1B for talented foreign nationals in technology, finance, scientific research, and entrepreneurship who cannot obtain H-1B cap selection.

O-1A criteria analysis under USCIS Policy Manual Volume 1, Part B, Chapter 4 requires the petitioner to demonstrate that the beneficiary has sustained national or international acclaim and that the beneficiary’s achievements have been recognized in the field through extensive documentation, either by evidence of a major, internationally recognized award (equivalent to a Nobel Prize level) or by evidence of at least three of eight regulatory criteria: (1) receipt of lesser nationally or internationally recognized prizes or awards for excellence in the field; (2) membership in associations in the field that require outstanding achievements as judged by recognized national or international experts; (3) published material in professional or major trade publications or other major media about the beneficiary and the beneficiary’s work in the field; (4) participation on a panel or individually as a judge of the work of others in the same or allied field of specialization; (5) original scientific, scholarly, or business-related contributions of major significance in the field; (6) authorship of scholarly articles in the field in professional or major trade publications or other major media; (7) display of the beneficiary’s work in the field at artistic exhibitions or showcases (relevant for business innovators whose products are featured at major industry conferences or showcases); and (8) a critical or essential role for an organization or establishment with a distinguished reputation, with a high salary or other remuneration for services that demonstrates exceptional accomplishment relative to others in the field.

The retained business immigration attorney advising on O-1A petition strategy evaluates each criterion against the beneficiary’s background to identify the strongest three or more criteria for the petition, develops the evidentiary strategy for each criterion (what supporting documents to obtain, how to present the evidence in the petition letter, and which expert opinion letters will most effectively contextualize the beneficiary’s achievements within the field), and drafts the petition letter that connects the beneficiary’s specific achievements to the regulatory criteria under the final merits determination standard established by the Supreme Court in Kazarian v. USCIS, 596 F.3d 1115 (9th Cir. 2010) — under which USCIS evaluates the totality of the evidence in a final merits determination after separately evaluating whether the evidence submitted qualifies under each individual criterion.

L-1A intracompany transferee advisory and EB-1C immigrant petition strategy

The L-1A nonimmigrant visa category under INA §101(a)(15)(L) allows multinational employers to transfer foreign national employees from a foreign affiliate, subsidiary, branch, or parent company to the U.S. entity to serve in an executive or managerial capacity. The L-1A category requires that the beneficiary have been employed by the petitioning employer or a qualifying related foreign entity in an executive or managerial capacity for at least one continuous year within the three years immediately preceding the petition filing.

Qualifying employment documentation for the L-1A petition requires the retained immigration attorney to document that the beneficiary’s foreign employment satisfies the executive or managerial capacity definitions under 8 CFR §214.2(l)(1)(ii): an executive capacity involves the beneficiary’s direction of the organization or a major component or function, establishment of goals and policies, exercise of wide latitude in discretionary decision-making, and receiving only general supervision from higher-level executives or the board; a managerial capacity involves the management of the organization, a department, subdivision, function, or component, supervision and control of professional employees (or management of an essential function), authority over personnel actions, and exercise of discretion over day-to-day operations. For staffing-intensive organizations (retail, hospitality, manufacturing) where the supervisory structure may not clearly support a first-line managerial capacity claim, the attorney evaluates whether the beneficiary manages a function rather than a team (the “function manager” theory recognized by USCIS) and whether the beneficiary’s subordinates include primarily professional-level employees. The EB-1C employment-based immigrant petition (for multinational managers and executives) uses the same executive and managerial capacity standards as the L-1A and is available to L-1A beneficiaries who wish to pursue permanent residence — with the significant advantage that EB-1C petitions are not subject to the PERM labor certification requirement and are processed with priority dates that are generally current or only slightly backlogged for most nationalities.

EB-1A extraordinary ability self-petition strategy

The EB-1A employment-based first preference immigrant category under INA §203(b)(1)(A) is available to individuals who have extraordinary ability in the sciences, arts, education, business, or athletics that has been demonstrated by sustained national or international acclaim, as evidenced by achievements recognized in the field through extensive documentation. Unlike most employment-based immigrant categories, the EB-1A allows self-petitioning: the beneficiary files the I-140 Immigrant Petition for Alien Workers without a sponsoring employer and without a PERM labor certification. The extraordinary ability standard for EB-1A is the same standard used for the O-1A nonimmigrant category, evaluated using the same ten regulatory criteria (adapted for immigrant petition purposes) under the Kazarian final merits determination framework.

EB-1A self-petition strategy requires the retained immigration attorney to evaluate whether the beneficiary’s extraordinary ability evidence is sufficiently strong to support an EB-1A self-petition without an employer sponsor — a practical advantage that is particularly significant for foreign nationals who are between jobs, who work as independent contractors or consultants, or who are in employment situations that make employer-sponsored immigration impractical. The attorney evaluates the beneficiary’s evidence against a minimum of three of the ten EB-1A regulatory criteria (prizes and awards, membership in associations, published material, judging others’ work, original contributions, scholarly articles, display of work, critical or essential role, high salary, commercial successes), identifies which criteria are clearly satisfied and which require additional evidence development (for example, obtaining expert opinion letters from leading figures in the beneficiary’s field to contextualize the significance of the beneficiary’s contributions), and advises on whether the final merits determination evidence (the totality of the evidence demonstrating that the beneficiary has sustained national or international acclaim) is sufficiently compelling to withstand USCIS scrutiny.

Immigration compliance advisory

Immigration compliance advisory is the retainer function that manages the employer’s obligations under the immigration enforcement statutes and regulations that govern the employment of foreign nationals: the I-9 employment eligibility verification system, H-1B public access file maintenance and worksite compliance, and ICE audit and DOL investigation response. Employers who fail to comply with I-9 requirements or H-1B compliance obligations face civil money penalties, back-pay liability (for underpaid H-1B workers), debarment from sponsoring future H-1B workers, and — in cases of knowing and willful violations — criminal prosecution.

I-9 employment eligibility verification compliance under 8 U.S.C. §1324a

The I-9 employment eligibility verification requirement under 8 U.S.C. §1324a requires all U.S. employers to verify the employment authorization of all employees hired after November 6, 1986, by completing a Form I-9 for each employee at the time of hire. The employer must examine the employee’s documentation establishing both identity and employment authorization (List A documents, or a combination of List B identity documents and List C work authorization documents), record the document information in Section 2 of the Form I-9, and retain the completed I-9 for the later of three years after the date of hire or one year after the date of termination.

Remote inspection procedure for remote employees under the DHS remote I-9 inspection pilot (authorized by DHS regulations and extended through alternative procedure options for E-Verify enrolled employers) allows employers to inspect I-9 documents virtually rather than in person for employees who work exclusively remotely, provided that the employer: examines the employee’s documents via live video interaction at the time the employee presents the documents for inspection (not by accepting photographs or scanned copies of documents without a live interaction); retains clear, legible copies of all documents examined during the virtual inspection; and notates “remote inspection” in the Additional Information field of the Form I-9. The retained immigration attorney advising on remote I-9 compliance develops procedures for the employer’s remote workforce that satisfy the DHS alternative procedure requirements — including scripted procedures for video inspection calls, document image retention protocols, and instructions for HR coordinators who conduct remote inspections.

Reverification procedures for employees with temporary employment authorization require the employer to reverify the employee’s continued employment authorization before the expiration of the employee’s work authorization document. Employers may not request a specific document for reverification (an employer may not require a renewal of the same document type presented at initial hire); the employer must accept any List A or List C document the employee chooses to present for reverification. Reverification is completed in Section 3 of the existing Form I-9 (or, if Section 3 has already been used, on a new Form I-9 with the employee’s name and A-Number from Section 1 carried forward). The retained immigration attorney advising on a reverification calendar system develops a 90-day advance notice protocol that alerts the employer’s HR team to approaching work authorization expirations across the sponsored workforce — including H-1B workers whose H-1B approval notice and I-94 have a specific expiration date, OPT EAD holders whose 12-month or 24-month STEM OPT extensions expire on specific dates, and employees on H-4 EADs whose work authorization is tied to the principal H-1B beneficiary’s status.

H-1B compliance: LCA posting, public access file, and worksite compliance

H-1B employers are subject to ongoing compliance obligations beyond the initial petition filing: LCA public access file maintenance, worksite posting requirements, and compliance with the H-1B worker’s right to receive the wages and working conditions stated in the approved LCA regardless of the worker’s specific worksite location.

LCA public access file maintenance under 20 CFR §655.760 requires the H-1B employer to maintain a public access file (PAF) for each LCA filed, and to make the PAF available to any member of the public who requests it within one business day of the request. The PAF must contain: a copy of the certified LCA; documentation of the wage rate paid to the H-1B worker; documentation that the employer has provided notice of the LCA filing (either through individual notice to employees in the same occupational classification or through electronic notification in the workplace); and documentation of the benefit package offered to H-1B workers compared to similarly employed U.S. workers. The retained immigration attorney auditing an employer’s PAF compliance reviews whether PAFs are maintained for all current H-1B LCAs, whether the PAF documentation is complete and up to date for current H-1B workers, and whether the employer’s PAF production procedures (identifying which employee is responsible for PAF maintenance and how public requests will be handled) are adequate.

H-1B worksite compliance for consulting placements under 20 CFR §655.734 is a significant compliance risk for employers who place H-1B workers at client or third-party worksites (a common practice for technology staffing firms, IT consulting firms, and professional services firms). The employer’s LCA is filed for the specific geographic area of the worksite where the H-1B worker will be employed; if the H-1B worker is placed at a client worksite in a different geographic area than the LCA worksite, the employer must file a new LCA for the new area of employment and post the new LCA at the new worksite. The USCIS regulation at 8 CFR §214.2(h)(2)(i)(B) also requires that for H-1B workers who will be placed at third-party worksites, the petition must include a complete itinerary of services or engagements if the worker will be moving from worksite to worksite — a requirement that USCIS has used as a basis for RFEs and denials in “benching” situations (where an H-1B consulting worker is not assigned to a client project for a period of time). The retained immigration attorney advising on consulting worksite compliance develops a tracking system for the employer’s H-1B workers’ worksite locations, identifies H-1B workers who have moved to worksite locations not covered by their existing LCAs, and advises on the H-1B worker’s rights under 20 CFR §655.801 including the right to receive the required wage even during periods when the worker is “benched” (not placed with a client) and the whistleblower protection provisions that prohibit retaliation against H-1B workers who complain about wage violations.

Tracking business immigration retainer hours with a shared dashboard

Business immigration attorneys and corporate immigration counsel on monthly retainer perform the advisory work between USCIS petition filings, PERM certifications, and ICE audits that determines the employer’s immigration strategy, maintains compliance with employer obligations, and positions the sponsored workforce for permanent residence. That advisory work (H-1B cap lottery analysis, O-1A criteria assessment, I-9 audit preparation, LCA prevailing wage evaluation, EB-1A self-petition development) generates no visible USCIS filing or government correspondence for the client’s HR or legal team until a specific filing milestone or enforcement event is reached.

A retainer dashboard that gives the client’s HR director real-time visibility into the business immigration attorney’s time allocation — which immigration matters consumed the month’s hours, which visa status expirations are approaching, which I-9 compliance gaps were identified and remediated — transforms the retainer from an opaque monthly fee into a documented immigration advisory record. The work log that accompanies each entry (immigration matter, applicable INA provision or CFR regulation, finding or recommended immigration strategy, hours spent) provides the client’s HR and legal teams with a running account of the immigration advisory activity that explains the retainer fee in terms of specific immigration outcomes and employer compliance risk mitigation.

HourTab provides a public, no-login retainer dashboard URL that the business immigration attorney sends to the client once and the client’s HR director or GC bookmarks. The dashboard shows the current retainer burn-down (hours used vs. hours remaining in the cycle), a chronological work log of entries from the immigration attorney, and the reset date for the next billing cycle — eliminating the monthly “how many hours do I have left?” inquiry and giving the HR director a self-serve view of the immigration advisory utilization between the attorney’s monthly billing statements.

Frequently asked questions

What does a business immigration attorney on retainer typically do?

A business immigration attorney on monthly retainer provides ongoing advisory across employment-based immigration (H-1B cap lottery strategy and LCA prevailing wage determination, O-1A extraordinary ability criteria analysis and petition strategy, L-1A intracompany transferee advisory and EB-1C immigrant petition strategy, EB-1A extraordinary ability self-petition strategy, and PERM labor certification advisory) and immigration compliance (I-9 employment eligibility verification compliance including remote inspection procedures and reverification calendars, H-1B public access file maintenance and consulting worksite compliance, and ICE Notice of Inspection response strategy). The retained attorney monitors the client's sponsored employee visa portfolio, advises on immigration implications of workforce changes, and coordinates the timing of immigrant petition filings with DOS Visa Bulletin priority date movements.

What business immigration advisory work is most commonly underlogged?

The most systematically underlogged categories are: H-1B cap planning and specialty occupation analysis (evaluating each position and candidate for cap registration, specialty occupation compliance, and alternative visa category availability — takes 8 to 20 hours per candidate group and produces no visible USCIS filing until the April 1 petition window); O-1A criteria analysis (evaluating all eight O-1A criteria under USCIS Policy Manual Vol. 1 Part B Ch. 4 and developing the evidentiary strategy — takes 10 to 20 hours per candidate and produces no visible output until the O-1A petition is filed); I-9 compliance auditing (reviewing I-9 records for technical and substantive violations, developing reverification calendars — takes 10 to 30 hours per compliance cycle and produces no visible output until an ICE NOI is received); and PERM labor certification strategy (position analysis, job requirements, and recruitment procedure design — takes 15 to 40 hours per PERM position and produces no DOL filing until the ETA Form 9089 is submitted).

What should a business immigration attorney retainer agreement include?

Business immigration attorney retainer agreements should specify: services covered (H-1B, O-1A, L-1A, TN, E-3 nonimmigrant advisory; EB-1A, EB-1C, EB-2 NIW, PERM EB-3 immigrant petition advisory; I-9 and H-1B compliance advisory; or a defined combination); applicable legal frameworks (INA 8 U.S.C. §§1101-1537; DHS regulations 8 CFR; DOL LCA regulations 20 CFR Part 655; DOL PERM regulations 20 CFR Part 656; USCIS Policy Manual; INA §274A I-9 employer sanctions); deliverables format (H-1B petition packages with LCA, specialty occupation analysis, and supporting evidence; O-1A petition packages with criteria analysis matrix; EB-1A petition packages; I-9 compliance audit reports; ICE NOI response packages); and the work log format giving the client's HR and legal teams visibility into immigration advisory activity between USCIS filing and enforcement milestones.

What are typical retainer rates for business immigration attorneys?

Immigration associates and counsel with 3 to 7 years of experience typically bill at $275 to $475 per hour. Senior business immigration partners with 8 or more years of experience typically bill at $425 to $750 per hour. Monthly retainer amounts for ongoing corporate immigration portfolio management typically range from $3,000 to $12,000 per month for technology companies with 20 to 100 sponsored employees; companies with more than 100 sponsored employees typically negotiate fixed annual retainer fees of $50,000 to $200,000 or more depending on portfolio complexity. Active ICE audit or DOL wage investigation retainers typically range from $10,000 to $40,000 or more per month during active enforcement phases.

How should business immigration attorney retainer hours be logged?

Business immigration retainer work log entries should capture: the immigration matter (H-1B cap planning, O-1A petition advisory, L-1A petition advisory, EB-1A self-petition strategy, I-9 compliance, PERM labor certification advisory), the specific immigration task, the applicable INA provision, CFR regulation, or USCIS policy analyzed, and the finding or recommended strategy. A useful format is: [Immigration Matter] + [Specific immigration task] + [INA provision or CFR regulation analyzed] + [Finding or recommended strategy]. Entries that identify the specific O-1A criteria analyzed for each candidate, the I-9 violation type and corrective action, and the LCA prevailing wage level determination rationale transform the immigration compliance retainer from a general immigration advisory agreement into a documented advisory record between USCIS petition filings, PERM certifications, and ICE inspections.
