1,遞交485後除了等信,還有什麽其他的方式能知道USCIS關於自己案子的情況更新嗎? 如Email,在485表上沒看到填Email的地方
-You need to file G-1145 with the I-485 filing so that USCIS can email you about your case status.

2,遞交485能不能用PO BOX 作收信地址?
-No. USCIS wants a physical address where you stay and will not deliver mail to PO box. Especially, sometimes USCIS needs the applicant's signature to confirm the mail has been received.
There is no forwarding of documents sent by USCIS too. They are all returned to USCIS if no one receives it in the applicant's address.
