你說的不對,回複：回複：小白兔，大俠們：離美後，才收到AP,回美是能

H1B回國應該是可以不需要申請AP的,回國不會void 485.
Correct me if i am wrong.

To reenter the United States, each foreign national will need certain documents establishing eligibility for the status or classification that s/he is seeking. For nonimmigrants, this usually includes a visa stamped in the passport in the appropriate classification. A person who intends to return to work in the U.S. in H1B status, for example, should have a valid H1B visa stamped in the passport, an original or a copy of the H1B approval notice, a letter from the employer confirming the ongoing need for the person, and pay stubs to establish that the person was working before s/he left the U.S. A person with a pending Application for Adjustment (I-485), if not entering in L or H status, must have an AP document. A permanent resident will need to show a valid (or un-expired) green card or an I-551 "temporary evidence" stamp in the passport, if s/he does not have the physical card. An immigration attorney should be able to discuss the documents needed for each type of traveler to reenter the U.S.
