If your U.S. mailing address used on your OPT or STEM OPT application changes while waiting for your application to be processed, you must update your
USCIS account as soon as possible. Failure to do so means you will not receive any correspondence from USCIS, and your approved EAD will be "undeliverable."
Also, as a separate step, please update ISP with any address changes while your application is being processed via ISP's
SEVIS Update Form. Keep in mind that address changes made to your SEVIS record will not transfer to your USCIS application, so you must update USCIS directly.
Include U.S. street address (with apartment number), city, state and zip code.
