回複：USCIS是否能收回已發出的綠卡?

USCIS是否能收回已發出的綠卡，
- Yes

即便是他們自己的錯誤，
- 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，那申請人的狀態又將會如何，
- illegal stay

該怎樣應對，
- Leave the country, or have USCIS promptly reinstate prior status

得找律師嗎？（＄＄＄）。
- up to you
