回複：H1在485pending期間回國的問題？

1. There will be always some risk if you apply for a visa. However, H1 may have better chances than other kinds of visas. Be sure you bring all the documents.
2. It may be complicated if you want to re-schedule the FP. In fact, you can go to INS before the FP date to do an "early FP". An immediate international travel is a good reason to do so.
3. No.
4. Without an AP, if you go outside of USA, your I-485 will be invalid. So you have to wait until you get your AP in hands.
