Q. What are the procedures for requesting an expedited adjudication of Form I-131?
A. If applicants require expedited processing, the instructions provide specific information for submitting pre-paid express mailers with the Form I-131 for USCIS to send the applicant his or her receipt and ASC appointment notice, as well as the completed re-entry permit or refugee travel document, if approved. A request for expedited processing should contain the applicant’s reasons for such processing so that USCIS may determine whether the applicant qualifies for expedited processing.
