You said "这个不同的概念，只有在 AP 入境之后 I-485 被拒的情况下，才出现分歧。如果是仍旧的 H 非移民身份，就可以继续在境内停留；如果死扣移民局的 Memo，这时候申请人必须手动地进行 H 的 reinstatement，尽管原来的还没有到期。"
So if a H1B returns to US using AP, in the event of I485 denial he/she can reinstate to H1B. Is that correct? What kind of application must be filed in that case to reinstate H1B?
Many thanks.
