USCIS 拿STAMP不成功的话(USCIS说再查什么的),这时可以用AP回国再入境吗?
-Techincally, no. If you are in China before the I-485 is approved, you can use the AP to come back even if the I-485 is approved. But in your current case, the AP is invalid. You may call USCIS for the card production status. You may try to get the green card stamp in local office some time later if you still do not get the card.
机票是20天后的,怕来不及。肯请帮忙,谢谢!!!
