My lawyer filed EB2 I485/EAD/AP for me and EAD/AP for my hu*****and who is currently F1. Today, I received her letter saying "Please remember that you cannot leave US without AP until we receive a decision on your Adjustment of Status applications. If you do leave, and this includes going to Canada, your Adjustment of Status applications will be terminated, and you will be unable to process for immigration in US. Additionally, you will not be allowed to re-enter the US until you processing with a US consulate in China." It sounds different from what I've seen somewhere here that the applicant has to be in the U.S. when the filing is received by USCIS. I did a key word search and only found similar questions without answers posted. Can someone help to clarify? Thanks a lot!
