回复：USCIS是否能收回已发出的绿卡?

USCIS是否能收回已发出的绿卡，
- Yes

即便是他们自己的错误，
- regardless
Mostly it is involved with PD, say I-485 was filed, or approved, when PD not being current

假如一定要收回，那申请人的状态又将会如何，
- illegal stay

该怎样应对，
- Leave the country, or have USCIS promptly reinstate prior status

得找律师吗？（＄＄＄）。
- up to you
