回複：回複：回複：綠卡收到,一看傻了,性別錯了,11月6號的機票回中國,急問怎麽辦

就是說我直接帶我媽拿她綠卡和護照還有出生證明,到USCIS local office他們就會給蓋那個章麽?

-Yes. Explain the error to the officer and they will stamp your mother's passport.

不用預約什麽的麽,,,謝謝您啦

-If she has enough time, had better make an appointment by infopass at this website:

https://infopass.uscis.gov/infopass.php If has no time, just walk in. 

還有就是我媽之前收到的AP沒用了是嗎?

-The AP is invalid.

他們要是和我回國超過6個月怎麽辦,回

-The stamp is valid for one year.
