A permanent resident card, popularly known as a green card, is issued upon approval by U.S. Citizenship and Immigration Services. Your green card serves as evidence of your right to live and work in the United States permanently. If some time has passed and you still don't know whether your application was approved or denied, you can check your case status with USCIS.
Check Status Online, By Phone or in Person
You can check your case status online by visiting https://egov.uscis.gov/casestatus. You'll be prompted to enter your receipt number. This is the number USCIS provided to you after it received your green card application. Receipt numbers make it possible for USCIS to identify and track the various cases it handles. It begins with three letters followed by 10 numbers. You can also check on your case status by calling USCIS at 800-375-5283 and providing your receipt number when prompted. To speak to someone in person, make an appointment with your local USCIS field office online at https://infopass.uscis.gov/info_lang.php?sel_lang=en.
