---应该不会被拒的。我老公在递了485 和 AP 后回中国, 在AP批准之前在北京签H4 回美国, 然后再去中国,再拿AP入境。没有遇到麻烦
here the difference is that your hu*****and use H4 for the first trip, and use AP second time, so technically he LEFT US AFTER AP was approved.
assuming he didn't apply H4, and his AP was approved during his stay in China and try to use AP back for the first trip, very likely he will get trouble.
See difference ?
