TPS and Social Security Number

If I have TPS, can I apply for a Social Security number?

Yes, only noncitizens whom the Department of Homeland Security (DHS) has given special authorization to work in the United States can get a Social Security number. If you have  TPS and your application for authorization to work has been approved, you can get a Social Security Number.  Employers use Social Security numbers to report their employees’ wages to the government. The government then works out your Social Security benefits according to your employment history. You need a Social Security number to work, collect Social Security benefits and receive some other government services.
