Use this form to apply for a re-entry permit, refugee travel document, advance parole travel document (including parole into the U.S. for humanitarian reasons), or advance permission to travel for CNMI long-term residents.

If you file this form to request an advance parole document and depart the United States without having an advance parole document that is valid for the entire time you are abroad, we will consider your Form I-131 abandoned.
