Advance Parole (AP)

An advance parole is a travel document issued to an applicant with a pending i-485 adjustment of status case in order for him/her to return to the United States. If you leave the US without an advance parole, your i-485 will be considered abandoned.

However, there is an exception for people in H, L, K or V status: you may return to the US using either an AP or a valid visa (H1, H4, L1 or L2), and it won't jeopardize your AOS application.
