回复：烦!拿到AP律师还是建议我签H1B回来

刚在Hooyou网上看见这段话：

Q: I am an H-1B holder, and I have already filed an I-485. Do I need to apply for an Advance Parole?

A: No, you need not apply. As an H-1B holder, as long as you maintain a valid H-1B status before you leave the US, you may try to apply for a H-1B visa to reenter the U.S. after your travel abroad. When you come back to work for your H-1B sponsoring employer, you are considered as a parolee status and your I-485 is preserved. However, you do not need EAD to work.
Furthermore you can still apply for an extension of H-1B status or transfer H-1B status to bring you back into H-1B status from a parolee status.

“When you come back to work for your H-1B sponsoring employer, you are considered as a parolee status and your I-485 is preserved.” 即使用H签证回来，也是Parolee？那大家都用AP不就行了，没必要再申请签证了吧。

自己还有个问题，H1B在拿到AP前离美，是不是视为自动放弃AP的申请？还是USCIS还是会批准AP，可以等到下次离美时再用？
