AC21 Job Portability & 180-Day Green Card Safety Auditor
Are you stuck waiting years in EB-2 or EB-3 visa backlogs and considering a new job offer or internal promotion? Audit your exact 180-day I-485 safe harbor date, verify whether your approved I-140 is shielded from employer revocation under 8 C.F.R. § 204.5(p), and test your new SOC occupation code for USCIS "same or similar" compliance.

Under the 2017 DHS Final Rule, if your I-140 has been approved for 180 days, your former employer cannot revoke your priority date or kill your green card by withdrawing the petition.
Step 1: Form I-485 & Form I-140 Timeline Verification
Step 2: Compare Current vs. Proposed Job & SOC Code
Under USCIS Policy Manual Vol 7 Part E, portability requires the new job to be in the "same or a similar occupational classification" (INA § 204(j)).
I-485 Clock: Day 240 (Safe Harbor Passed on 2026-08-28)
Statutory Basis: INA § 204(j), 8 U.S.C. § 1154(j) & 8 C.F.R. § 245.25

STATUTORY SAFE HARBOR ELIGIBILITY (180 DAYS PENDING) As reflected on the official Form I-797C Notice of Action, the Beneficiary's Form I-485 Application to Register Permanent Residence or Adjust Status was received by USCIS on 2026-03-01. As of today, the application has remained pending unadjudicated for 240 calendar days, thereby satisfying the statutory condition precedent of 180 days (which was reached on 2026-08-28). Furthermore, the underlying Form I-140 Immigrant Petition for Alien Worker was approved on 2025-11-01. Under 8 C.F.R. § 204.5(p) and the DHS 2017 Final Rule, the approved petition has remained unrevoked for over 180 days and remains permanently valid for AC21 portability purposes. 2. SAME OR SIMILAR OCCUPATIONAL CLASSIFICATION Under USCIS Policy Manual (7 USCIS-PM E.5), job portability requires that the new employment offer be in the "same or a similar occupational classification" as the job for which the original petition was approved: - Original Certified Occupation: Senior Software Engineer (SOC Code: 15-1252) - New Permanent Offer of Employment: Lead Software Architect (SOC Code: 15-1252) - Offered Annual Remuneration: $165,000 per annum The new position requires equivalent foundational education, core competencies, and operational responsibilities as demonstrated in the attached detailed Job Duties Exhibit. CONCLUSION The Beneficiary has satisfied all statutory criteria set forth under INA § 204(j) and 8 C.F.R. § 245.25. Respectfully requested is the continued adjudication of the Beneficiary's Form I-485 adjustment of status application to approval.

How the 180-Day AC21 Portability Clock Works
Before Congress enacted the American Competitiveness in the Twenty-First Century Act (AC21), employment-based green card applicants were virtually bound to their petitioning employers until the final green card was physically approved. If an employer went out of business or the employee was laid off while waiting for an immigrant visa number, the entire multi-year labor certification (PERM) and I-140 process had to be restarted from scratch.
INA § 204(j) eliminated this indentured dynamic by establishing that an approved Form I-140 "shall remain valid with respect to a new job if the individual may have found employment with a new employer or in self-employment if the adjustment of status application (Form I-485) has remained unadjudicated for 180 days or more."
The 2017 DHS Final Rule: Protection Against Employer Revocation
One of the greatest fears for immigrant workers is employer retaliation: "If I resign, will my company withdraw my I-140 and destroy my green card?"
In January 2017, the Department of Homeland Security published a landmark Final Rule (codified at 8 C.F.R. § 204.5(p)). Under this regulation:
- If Form I-140 is withdrawn within 180 days of approval: USCIS automatically revokes the approval. If the worker does not have an I-485 pending that has reached 180 days, the underlying petition is lost.
- If Form I-140 is withdrawn after 180 days of approval: The I-140 remains valid for AC21 job portability and priority date retention. Even though the employer informs USCIS of the employment termination, USCIS does not revoke the petition approval for immigration benefits.
Demystifying the "Same or Similar" Standard Under SOC Codes
To determine whether an applicant's new position complies with INA § 204(j), USCIS adjudicators reference the Department of Labor Standard Occupational Classification (SOC) system. In its comprehensive Policy Manual (7 USCIS-PM E.5), USCIS outlines a structured hierarchy:
Moving from Software Developer (15-1252) at Company A to Software Developer (15-1252) at Company B. USCIS considers this prima facie similar. Approval is nearly automatic upon filing Supplement J.
Moving from Software Developer (15-1252) to Data Scientist (15-2051) or Systems Analyst (15-1211). Because both fall under Major Group 15-0000 (Computer and Mathematical), USCIS recognizes common training, coursework, and day-to-day duties.
Moving from Senior Engineer (15-1252) to Engineering Manager (11-3021). USCIS Policy Manual explicitly permits promotions into management, provided you manage workers performing your original technical specialty.
Frequently Asked Questions About AC21 Portability
Section 204(j) of the Immigration and Nationality Act (INA), enacted under the American Competitiveness in the Twenty-First Century Act (AC21), allows an employment-based adjustment of status applicant (Form I-485) to change jobs or employers without invalidating their approved Form I-140 petition, provided the Form I-485 has been pending for at least 180 days and the new job offer is in the "same or a similar occupational classification."
Under the DHS 2017 Employment-Based Immigration Final Rule (8 C.F.R. § 204.5(p)), if an approved Form I-140 has been approved for at least 180 days, any subsequent withdrawal or business termination by the petitioner does NOT automatically revoke the petition for AC21 portability or priority date retention purposes. Even if the former employer formally requests withdrawal, your I-140 remains valid for your pending I-485.
USCIS adjudicators consult the Department of Labor Standard Occupational Classification (SOC) system and USCIS Policy Manual (Volume 7, Part E, Chapter 5). Jobs sharing the same SOC Broad Group or Minor Group (such as 15-1250 Software and Web Developers) are presumed similar. For career promotions (e.g., Software Engineer to Engineering Manager), applicants must establish that the new managerial role oversees the original technical specialty and retains significant hands-on technical responsibilities.
Form I-485 Supplement J (Confirmation of Bona Fide Job Offer or Request for Job Portability Under INA Section 204(j)) may be filed proactively once you start employment with your new sponsor, or in response to a USCIS Request for Evidence (RFE) or interview notice. Most immigration attorneys recommend filing proactively to ensure the adjudicating service center has updated employer records on file.
Yes, USCIS Policy Manual permits AC21 portability to self-employment, but it attracts heightened scrutiny. You must prove the business is viable, active, has the financial ability to pay the offered wage, and that a bona fide employer-employee relationship exists (typically through a separate corporate board or operating agreement).
