AC21 Portability 2026: Should You File I-485 Supplement J Proactively or Wait for RFE?

For employment-based green card applicants whose I-485 has been pending for more than 180 days, AC21 portability offers a critical safety net when changing employers. AC21 (American Competitiveness in the Twenty-First Century Act) allows applicants to move to a same or similar occupational classification without jeopardizing their pending adjustment of status application. The central question addressed in this Murthy Law Q&A is whether applicants should proactively file Form I-485 Supplement J when invoking AC21 portability, or wait until USCIS issues a Request for Evidence (RFE). This is a nuanced procedural decision that can significantly impact the outcome of an adjustment of status application. Generally, USCIS regulations and policy guidance allow applicants to submit Supplement J either proactively or in response to an RFE. Proactive submission can help establish a clear record of the employer change and demonstrate eligibility under AC21 before any questions arise from an adjudicator, potentially streamlining the review process. For EB-3 applicants navigating this decision, the key considerations include the similarity between old and new job duties, the timing of the employer change relative to the 180-day threshold, and whether the new position falls within the same occupational classification. Documentation of the new position's duties and salary should be prepared regardless of the submission strategy chosen. Applicants are strongly advised to consult with an immigration attorney before making this decision, as the specifics of each case—including the applicant's priority date, country of chargeability, and job description—can influence the best approach.
