回复：请教8老师一个问题。

我帮我母亲在美申请绿卡，可是等了10月还没有下来，老人家呆不住了，身体又不好，想回国，所以想放弃绿卡了，我的问题是回去后我母亲还可以用B2 再申请来美国吗？多谢！
-If she leaves US now, it is difficult for her to get the B2 visa in the future due to immigration intent. My suggestion is that she had better use advance parole (AP) to travel to China and if she has been interviewed, and has conducted the biometrics, she just needs to come back before the AP expires. If she has no AP in hand and wants to leave US very soon, she may just go to the USCIS local office to see whether she can get the AP. At the same time, she can file I-131 to USCIS to get the regular AP if she can wait for a few months.
