When you board the plane for your return trip to the United States, you must present the Parole to the airlines. When you arrive in the United States, you must present the Parole to the Immigration officials.
As the Parole is valid for multiple entries, please note that you must secure the return of all copies each time you present same to the appropriate officials.
Please note that in general, the primary Immigration Inspector does not process admissions to the United States based on Advance Parole Authorizations. Instead, you will most likely be forwarded to the “Secondary Inspection” area for processing. You need not be concerned – this is routine for the type of arrival in the United States.
