AC21 Job Portability: No Immediate Filing Required After Employer Change

AC21 (American Competitiveness in the Twenty-First Century Act) job portability allows I-485 applicants whose green card applications have been pending for 180 days or more to change employers or jobs without losing their place in the green card queue, provided the new position is in the same or similar occupational classification. Contrary to common concern, there is no requirement to file an AC21 portability notice immediately upon changing employers. USCIS does not require a specific form or filing at the time of the job change. The portability claim is typically invoked when USCIS issues a Request for Evidence (RFE) or Notice of Intent to Deny (NOID), or during the adjudication of the I-485. However, immigration practitioners generally advise applicants to prepare documentation proactively. This includes securing a new employer's job offer letter, updated job description, and evidence that the new role is in the same or similar occupational classification as the original petition. For EB-3 applicants specifically, ensuring the new position falls within the same SOC code or a closely related occupational category is critical. Having this documentation ready before USCIS inquires can significantly streamline the adjudication process. Applicants should consult with an immigration attorney to assess their specific circumstances, particularly if their new role differs substantially from the original petitioned position.
