The USCIS recently opened Case Status online letting customers with applications at a CIS Service Center conveniently check the status of their case over the internet. As a next step in improving service customers can also call 1-800-375-5283 toll-free for automated case status assistance on Service Center filed cases. This new number replaces the toll numbers previously used on receipt notices (Service Center numbers). This system is an automated replacement of the Service Center automatic case status system. Just follow the telephone menu directions if you call or click here.

Please be sure to have your application receipt number. The 13-character application receipt number can be found on application notices you have received from the USCIS. Dashes ("-") should be omitted when entering a receipt number. However, all other characters, including asterisks ("*"), can be included if listed on your notice as part of the receipt number.
