A) Approximately two weeks after Social Security Administration verify your immigration documents with the Department of Homeland Security (DHS) you will receive your Social Security card in the mail.
If SSA cannot verify your documents immediately online, it may take us several weeks to hear from DHS. We work closely with DHS to reduce delays
To follow up on your application for a Social Security number, wait 30 days after you applied and return to the Social Security office where you filed your application. When you go, take the documents you originally presented as evidence.
