回复：She may apply H4 but can not file 485 in China. - 回复：用过AP以后，妻

My experience: We filed 485. Went back to china using AP. I-94 said AOS. I extend my H1 after 6 years. But my hu*****and's H4 was denied. In the letter it said he can go to the nearest port of entry to get H4 again. I called the airport, they don't do it. I think he could go to the USCIS local office to get H4. But didn't try, so don't know if it is right.
