What changed
Section 106(c) of the American Competitiveness in the Twenty-First Century Act of 2000 (AC21), Pub. L. 106-313, enacted on October 17, 2000, gave certain employment-based green card applicants the right to change employers without restarting the immigrant petition process. The provision was codified at INA §204(j) (8 U.S.C. §1154(j)). Implementation matured in stages: the 2003 Yates memorandum first interpreted “same or similar occupational classification,” and USCIS’s Retention of EB-1, EB-2, and EB-3 Immigrant Workers final rule, effective January 17, 2017, formalized the procedural framework — including the requirement to file a job-portability supplement when the underlying I-485 is pending. The supplement is Form I-485 Supplement J. The current adjudicative standards live in USCIS Policy Manual, Volume 7 (Adjustment of Status), Part E (Employment-Based Adjustment), Chapter 5.
Why it matters
Without portability, an EB beneficiary whose I-485 has been pending for years would lose the petition (and the priority date) by changing jobs. Portability untethers the I-485 from the specific employer who sponsored the I-140 and lets the beneficiary continue toward green card approval at a new employer in a same-or-similar role — provided the I-140 was approved or approvable when filed, the new job is in the same or similar occupational classification, and the I-485 has been pending 180 days.
Practically, that gives the beneficiary leverage: long visa-bulletin backlogs in EB-2 and EB-3 (especially for India and China) make portability essential to professional mobility.
Way forward
A clean portability transition typically follows this checklist.
1. Confirm I-140 status. Portability requires either (a) an approved I-140 from the prior employer, or (b) an I-140 that was approvable when filed and remains valid. Under USCIS Policy Manual Vol. 7, Part E, Ch. 5, an approved I-140 generally cannot be revoked on the employer’s request once the underlying I-485 has been pending 180 days, except for fraud, willful misrepresentation, material error, or revocation of the labor certification.
2. Confirm 180 days of I-485 pending. Count from the I-485 receipt date. Day 181 is the first day the beneficiary may file Supplement J at a new employer in a same-or-similar role.
3. Verify “same or similar occupational classification.” The 2016 USCIS policy memorandum on §204(j) portability (PM-602-0122.1) and the Policy Manual treat occupational classification at the Standard Occupational Classification (SOC) code level. Same occupation means the same detailed SOC code; similar occupation means a different SOC code that shares substantial duties, education, and skills. USCIS evaluates job title, duties, required skills, education, training, and wage to decide.
4. File Form I-485 Supplement J. The 2017 rule requires Supplement J to confirm the bona fide job offer at the new employer and to invoke portability for the I-485. Supplement J should be filed at the time the beneficiary intends to port, signed by both the beneficiary and the new employer.
5. Maintain valid nonimmigrant status if needed. Many AC21 portability scenarios involve H-1B workers; AC21 §104 and §105 govern H-1B extensions past the 6-year cap and continue to require an approved I-140 or a labor certification filed at least 365 days before the cap deadline. Portability under §106(c) is independent of, but often intertwined with, those extensions.
6. Keep the prior I-140 audit trail. If the prior employer withdraws the I-140 after portability has vested (i.e., 180+ days after I-485 receipt), USCIS will treat the I-140 as valid for §204(j) purposes only — not for new I-485 portability or H-1B extensions tied to a separate filing. Document the dates carefully.
Edge cases
- Cross-preference portability. A beneficiary may port from an EB-3 job to an EB-2 job (or vice versa) only if the new role is in the same or similar SOC and the original I-140 remains valid; the priority-date retention question is separate and governed by 8 CFR 204.5(e).
- Self-employment. Portability to self-employment is permitted in principle under §204(j) if the new role is same-or-similar and the offer is bona fide. USCIS scrutinizes the bona fides closely.
- Promotion to a managerial role. A promotion that materially changes duties can take the new position outside the same-or-similar window even with the same employer. Supplement J is required when a same-employer promotion changes the underlying offer, per USCIS guidance.

This article is general information from a software company, not legal advice from a law firm. AC21 portability under INA §204(j) and the 2017 retention rule involve interlocking deadlines, SOC analysis, and form filings; a wrong date can cost the green card.
