USCIS announced that Deferred Action for Childhood Arrivals (DACA) recipients of employment authorizations documents (EAD) after February 16, 2015, with validity longer than two years, were “likely mistakenly issued and must be returned.” According to a USCIS Factsheet:

“Individuals who are required to return three-year EADs and have not done so will be contacted by USCIS by phone or in-person. For the purpose of retrieving these three-year EADs, USCIS may visit the homes of those individuals who have not yet returned their invalid 3-year EAD or responded to USCIS. When contacting individuals in person, the USCIS employees will show the individuals their credentials. USCIS will make every attempt to call the individual in advance of the visit…

The reason for this action is that, after a court order in Texas v. United States, No. B-14-254 (S.D. Tex.) was issued, USCIS could approve DACA deferred action requests and related employment authorization applications only for two-year periods.”

EADs mailed before February 16, 2015 are not subject to this requirement as they were issued before the court injunction.

Further information and contact details can be found on the USCIS factsheet.
