已收到i-751receipt letter,上麵有延期一年,但網上有說需持receipt letter到移民局蓋章才有效,也去過移民局,移民官說不需要蓋章就可以回中國再回美,移民官隻是口頭回答,有這方麵經曆的人,煩請指點
下,回美時會有麻煩嗎?
-Technically it is fine to use the I-751 Receipt notice and the expired conditional green card to travel, but I am not sure whether the Chinese Customs officers know and the airlines know this rule well.
