Department of Homeland Security: USCIS Advance Parole Documents (Fiscal Year 2016 Report to Congress) [open pdf - 391KB]
"This report responds to the Senate request to provide information on the use of advance parole documents. As requested, the report provides details on how many applications for advance parole documents were received by USCIS [U.S. Citizenship and Immigration Services] and, of those, how many applications were approved and denied. From FYs 2012-2015, USCIS received approximately 300,000 applications for advance parole documents each year. The majority of requests for advance parole documents comes from individuals seeking adjustment of status. Without conducting a manual review of each case, USCIS is unable to provide data on all deferred action recipients who obtained advance parole documents, because USCIS does not track electronically advance parole applications from recipients of deferred action that is not associated with the Deferred Action for Childhood Arrivals (DACA) policy. However, this report does include the number of DACA recipients who obtained advance parole documents and the number of applicants for adjustment of status (seeking lawful permanent resident status, commonly known as applying for a 'green card') who obtained advance parole documents. The report also provides data on the number of applications for which the filing fee was waived because of an inability to pay. The majority of applicants for advance parole do not receive a waiver for the filing fee."
