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 wanted to confirm with an expert before I leave.  Thanks!
