Considering this, can a Uscis number be used as a social security number?
To lawfully work in the United States, foreign workers in some categories and classifications need both an employment authorization document (EAD) from USCIS, and a Social Security number (SSN) from the SSA. For more information on applying for a Social Security card, see this fact sheet (PDF).
Secondly, is the a number the same as Uscis number? “A” number is short for Alien Registration Number. The 9-digit USCIS number listed on permanent resident green cards issued after May 10, 2010, is the same as the A-number. The A-number can also be found on the back of green cards.
Also know, is your alien registration number your Social Security number?
The Alien Registration Number isn't the same thing as a Social Security Number (SSN), which is used by the Internal Revenue Service and the Social Security Administration to keep track of U.S. workers' income, taxes, and benefits. You can apply for an SSN along with a work permit as part of your green card application.
Is green card number same as SSN?
It is the ID document which contains the 9-digit Social Security Number. The Social Security Card is usually only issued to employment-based or nonimmigrant visa holders or green card holders. The SSN is NOT to be mistaken with a legal resident permit.
