EB-3 Downgrade + AC-21 in 2026: How to Manage Two I-140s and Keep Portability Rights

A growing number of employment-based green card applicants are pursuing an EB-2 to EB-3 downgrade strategy—filing a second I-140 under the EB-3 category to take advantage of a current or nearer priority date, particularly for nationals of India and China where EB-2 backlogs extend decades. This creates a scenario where a single applicant holds two approved I-140 petitions simultaneously, raising important questions about how AC-21 job portability applies. AC-21 allows applicants who have had an I-485 pending for at least 180 days to change employers or job roles without jeopardizing their green card application, provided the new position is in the same or a similar occupational classification. When two I-140s are involved, however, determining which petition 'controls' portability—and how USCIS will adjudicate the I-485—requires careful analysis. The general principle is that USCIS evaluates the I-485 against the strongest available petition. If the EB-3 petition is the basis for the current filing (because its priority date is current), then AC-21 portability is assessed against the EB-3 job description and SOC code. Switching to a role that qualifies under EB-2 but not EB-3 could create ambiguity in how the agency treats the pending application. Practitioners advise that applicants in this dual-petition situation document any job change meticulously, obtain a same-or-similar occupation analysis from an immigration attorney before switching roles, and ensure the new employer is prepared to support both petitions if needed. USCIS may issue a Request for Evidence (RFE) probing the relationship between the two I-140s and the applicant's current employment. For EB-3 applicants navigating this in mid-2026, the July and August Visa Bulletins have kept some categories current intermittently, making priority date management and timely I-485 filing critical. Those with a downgrade strategy in place should review their petition status and consult counsel before making any job changes.
