已收到i-751receipt letter,上面有延期一年,但网上有说需持receipt letter到移民局盖章才有效,也去过移民局,移民官说不需要盖章就可以回中国再回美,移民官只是口头回答,有这方面经历的人,烦请指点
下,回美时会有麻烦吗?
-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.
