Are you a beneficiary of Temporary Protected Status (TPS) under Syria’s designation? If so, you must re-register between September 23rd and November 22nd if you plan to maintain your status through March 31st, 2021.
You can find the TPS re-registration procedures, including what you need to know about renewing employment authorization documents (EADs) here: https://www.uscis.gov/humanitarian/temporary-protected-status
If you want to renew your status, you will have to submit Form I-821, Application for Temporary Protected Status. You can also request an EAD you need by completing and submitting Form I-765, Application for Employment Authorization. You can do this when you file Form I-821.
The two forms can be found here: https://www.uscis.gov/forms
If you register and apply for an EAD during the re-registration period and you are still eligible for Syria’s TPS designation, you will be issued new EADs with a March 31st, 2021, expiration date. USCIS says it understands that “not all re-registrants will receive a new EAD before their current EAD expires on September 30th, 2019,” which is why the agency will “automatically extended the validity of those EADs for 180 days,” all the way through March 28th, 2020. If your EAD expired on March 31st, 2018, and you applied for a new EAD during the last re-registration period but haven’t received your new EAD, you are covered under the automatic extension.
Syria’s TPS designation was extended through March 31st, 2021 by Acting Secretary of Homeland Security Kevin K. McAleenan, who said “ongoing armed conflict and extraordinary and temporary conditions” in Syria made it necessary to extend the TPS designation for 18 months.
