AC21 Portability: What Counts as Same or Similar Job?
AC21 portability is one of the most powerful protections available to employment-based green card applicants — it lets you change employers after your I-485 has been pending for 180 days without losing your place in the queue. But the requirement that the new job be "same or similar" is where applicants run into trouble.
Frequently asked questions
What counts as same or similar job under AC21?
USCIS looks at the Standard Occupational Classification (SOC) code, job duties, skill requirements, and whether the two roles are in the same general occupational field. A senior version of the same role is always safe. A different functional role (engineer to manager, engineer to product manager) is more risky and should be reviewed by an immigration attorney.
Do I have to file I-485 Supplement J when I change jobs under AC21?
You are not required to file Supplement J proactively, but it is strongly recommended. Filing it after changing jobs puts USCIS on notice that you are using AC21 portability and reduces the chance of an RFE or denial based on job change. You can also wait and submit it in response to an RFE.
Can I change jobs before my I-485 is approved?
Yes, under AC21 you can change jobs after the I-485 has been pending for 180 days and your I-140 is approved. Before 180 days, changing jobs puts your I-485 at serious risk. After 180 days with a same or similar job, your green card case continues with the new employer.
