Question .My I-485 is pending, but I want to leave the employer that sponsored my green card. Can I do that?
The AC21 portability law permits a beneficiary to change sponsoring employers if the beneficiary's I-485 has been pending at least 180 days with the USCIS and the beneficiary moves to a job that is in the same or similar job classification, as described in the labor certification (or I-140 if no labor certification is needed). It is best if the I-140 is approved before AC21 portability is used, otherwise, it can be risky.
