Teacher, this will be my first time traveling back to China with the PR status. Right now my I-751 case is still in pending status and as you suggested before, I have made an InfoPass and got a passport stamp from USCIS office. With my expired conditional GC, extension letter and stamped passport, I should be all set for traveling out and into the US, right?
-Just need your passport which has the green card stamp and that is all. Of course, not hurt you to bring the extension letter also (the expired green card is useless now).
just wanted to confirm with an expert before I leave. Thanks!
