The Self Check process has four steps and three of them will require some information from you, the user.
Step 1 requires identifying information such as your name, date of birth, and address.
Step 2 requires you to answer demographic and/or financial questions. These questions could include information about past addresses, banks where you do businesses, or other information. They are being asked to confirm your identity before we let you continue with the Self Check process. The government will have no knowledge of which questions are presented or how those questions are answered.
Step 3 requires information that will prove your eligibility to work in the United States. This will include your Social Security number and, based on your citizenship status and documentation, information such as your Alien Registration Number, document number, or I-94 Number.
Step 4 does not require you to provide any personal information.
