Since my hu*****and and I are all using our OPT to work, and our H1-B will be effective in Oct. Is there any hidden risk when we our 485 now? Say, if I 140 was rejected before Oct, 1, will we lose legal status to stay in USA? Do we need to come back to China to have our H1-B activated? And do we need to other paperwork after Oct 1,say, F1 transfer to H1-B? Thank you!
