I am wondering whether I can bring only one original AP with me. Thus I will still have one in the case I loss my AP in China.
If I loss AP while I am outside of US ( of course, the chance is low but may happen), is there anyway I can enter US ( I am on AOS only, not other visa).
As we all know, no matter where I loss the passport, there would be a way for me to get a new one. If I am in US, I also can get an AP if I loss it. But how about outside of US, I am thinking it is unresonable if USCIS give zero tolerance for lossing AP outside of US.
