-Provide the the USCIS email indicating your AP approval, your AP application receipt (if possible), the approved AP and this letter to the CBP officer when you return and explain it to the officer (if necessary). I think you will be OK.
移民局的通知批准电邮是08/27发给我的,而我8/26离美,单就这一点有问题吗?
万一有问题,移民局8/23写给我的关于我8/20电话expedite request for extreme emergent need的信能够作为证明:我是因emgergency才提前一天离美吗?如果因emgergency在AP批准前离美,CBP officer能原谅我吗?(我会附上application receipt,the approved AP)。
-The issue date is the approval date. Obviously, it was an error in your AP issue date.
需要打电话报告错误,并更正吗。现在北京,更正麻烦吗?谢谢。
