If you request either initial or renewal Deferred Action for Childhood Arrivals (DACA), you must submit Form I-765, Application for Employment Authorization and required fees. USCIS will reject your request if you fail to submit Form I-765, the required filing fee, Form I-765 Worksheet, and Form I-821D, Consideration of Deferred Action for Childhood Arrivals. For complete instructions on requesting DACA, go to the Consideration of Deferred Action for Childhood Arrivals (DACA) page.
For DACA renewals, USCIS strongly encourages you to submit your renewal request between 150 days and 120 days before the expiration date located on your current Form I-797 DACA approval notice and Employment Authorization Document. Filing during this window will minimize the possibility that your current period of DACA will expire before you receive a decision on your renewal request.
USCIS’ current goal is to process DACA renewal requests within 120 days. However, you may submit an inquiry about the status of your renewal request after it has been pending more than 105 days.
