What Is AC21
AC21, formally the American Competitiveness in the 21st Century Act of 2000, is a federal law that allows employment-based green card applicants to change jobs or employers without losing their place in the green card queue. Under AC21, once you have an approved immigrant petition and a priority date that is current (meaning a visa number is immediately available), you can switch to a different employer in the same or similar occupation without requiring a new labor certification or a new PERM application.
This protection applies to workers in employment-based categories EB-2 and EB-3 who are in adjustment of status or consular processing. The law essentially decouples your green card application from your original sponsoring employer, giving you genuine career mobility during what can be a multi-year waiting period.
Key Eligibility Requirements
- Priority date must be current: Your priority date must be immediately available according to the USCIS Visa Bulletin. If your priority date is not yet current, you cannot use AC21 portability, even if your employer offers it.
- Same or similar occupation: Your new job must be in the same occupation or closely related field as listed in your approved immigrant petition. USCIS interprets "same" broadly but will deny AC21 if the new role represents a significant departure from your original job description.
- Approved petition required: Your Form I-140 (Immigrant Petition for Alien Worker) must be approved before you can port to a new employer. A pending petition does not qualify.
- Active employment status: You must remain employed by either your original employer or your new employer throughout the green card process. Gaps in employment can trigger USCIS scrutiny and potentially jeopardize your application.
- EB-2 or EB-3 categories only: AC21 protability applies only to employment-based categories 2 and 3. EB-1 and EB-5 applicants do not have access to this protection.
How to Use AC21
To invoke AC21 portability, notify USCIS of your job change. If you are in adjustment of status and have already filed Form I-485, include documentation of the new job offer and your new employer's evidence of ability to pay (typically recent tax returns and a letter confirming your employment terms). File this information as an unsolicited update to your pending I-485 case.
If you are in consular processing, you can change employers before your visa interview. Bring evidence of the new job and employer's financial capacity to your interview appointment.
Critical point: AC21 does not require your new employer to file any petitions or go through PERM labor certification again. This is the time and cost advantage of portability. However, USCIS will review the new job to confirm it meets the "same or similar" test. Significant changes in job title, duties, salary, or work location can trigger a Request for Evidence (RFE) or even a denial.
Common Questions
- Can I use AC21 if my priority date is not yet current? No. AC21 portability only applies once your priority date becomes current. If your priority date is years away, you cannot port to a new employer, even if the new employer is willing to sponsor you. You would need a new green card petition and labor certification from that employer.
- What counts as "same or similar" occupation? USCIS looks at whether the job duties, required qualifications, and industry context are substantially aligned with your original approved petition. A software engineer porting to a different company as a software engineer is clearly "same." Moving from a software engineer role to a business analyst role is riskier and may be challenged. When in doubt, consult an immigration attorney before accepting the new position.
- Do I need to notify my original employer when I use AC21? Not legally, though practical considerations matter. If your original employer learns you have moved to a competitor, they may withdraw the approved petition, which could complicate your case. Many applicants handle this carefully or with attorney guidance to manage timing and communication.
