Due to the government shutdown, USCIS is not able to update versions of their application forms. USCIS will, however, continue to accept all those expired versions of forms until new approvals can be obtained when the shutdown is over.
In other words, all USCIS forms, including the DACA application, that have an expiration date that falls during the government shutdown will continue to be accepted until a new version can be approved once the shutdown is over.
DACA, or the Deferred Action Childhood Arrivals, form of relief will remain valid despite its facial expiration date of January 31, 2019 until further notice and until the Supreme Court addresses it. Renewals of DACA applications can be filed up to 180 days prior to their expiration and USCIS will process them as they are received.
