Online at the USCIS website: A simple way to check the status of your pending case is to go to the USCIS website: USCIS Check Status. You will need your 13-character receipt number (ex. WAC-01-234-56789) in order to check online.
If you do not have the receipt number available, call USCIS at 1-800-375-5283 and explain your situation. Visitors to the U.S. seeking a change of status, resident alien status (green card), employment authorization or citizenship must file a petition with the USCIS. When any application is made to the USCIS, the agency will respond with an application notice that will bear an application receipt number.
