Using a SSN is a crime, which can lead to jail time and deportation from the United States. What if a person uses someone else's SSN? can lead to very serious criminal penalties. Even using an SSN with someone else's permission, such as a family member, is not permitted.
As a general rule, any non-citizen with a valid Form I-766 Employment Authorization Document (EAD) is eligible for a Social Security number (SSN).
If someone uses your SSN to obtain credit, loans, telephone accounts, or other goods and services, contact the Federal Trade Commission (FTC). The FTC collects complaints about identity theft from those whose identities have been stolen.
