2007年我和女儿一起申请了I-485.由于她不能在境内调整身份，
-What happened?
09年我给她交了I-824申请。去年10月，我们收到了移民局寄来的绿卡。
-If she was not qualified for the I-485 and USCIS approved it mistakenly, her green card technically is invalid.
12月，我女儿持我寄给她的绿卡来美国一趟之后，又回国了。
今天我收到移民局寄来的I-824 approval notice. 请问，她的绿卡有效吗？她需要去大使馆重新申请绿卡吗？
-You had better consult a lawyer for advice. In my opinion, your child had better return to USCIS if the I-485 was the USCIS mistake and then, apply for the immigration visa to avoid any potential trouble in the future.
