Social Security card

When a number is requested in the immigration process, DHS sends the data to SSA, SSA assigns the number and mails the card to the address you gave, or to your sponsoring agency if you had no address [source, source].

• SSA treats refugees as having permanent work authorisation and issues an unrestricted card (no legend) [source].
• One document can prove age, identity and status, for example the I-94 website printout with the State Department transportation boarding letter carrying the refugee admission stamp [source].
• An I-94 with the refugee admission stamp, or an EAD with category A3, is also accepted [source].
