On September 5, 2017, the Trump Administration rescinded the Deferred Action for Childhood Arrivals (DACA) program. DACA gave work permits to undocumented immigrants who came to the United States as children and met other stringent background checks and qualifications. No new DACA applications have been, or will be accepted by USCIS since September 5, 2017. Because DACA work permits were renewable every 2 years, renewal DACA work permits that were pending on September 5th will be processed by USCIS.
If your DACA work permit expires on or before March 5, 2018, then you still have until October 5, 2017 to submit your renewal application. October 5, 2017 is a strict deadline, and no renewal applications will be accepted after that date. Those DACA work permits that expire after March 5, 2018, will end on their expiration date.
Every DACA recipient should check the date their DACA or renewed DACA work permits expire and immediately renew if that date is on or before March 5, 2018. Speak to a qualified immigration attorney if you have questions regarding your DACA status.
