Advance parole
Advance parole (Form I-512) is an immigration document issued by the United States. It allows certain aliens to be paroled into the United States. It is not a re-entry permit; it is only issued to aliens without permanent residency. Advance Parole is permission for certain aliens, who do not have a valid immigrant visa, to re-enter the United States after traveling abroad. Such aliens include those who have applied to adjust their status to that of permanent resident or to change non-immigrant status. Advance parole must be approved before the applicant leaves the United States, or any residency application will in general be denied.

an application for adjustment of status pending.
