How do I apply for a Social Security number in the USA?

The Intern / Trainee has to apply for the Social Security Number at the nearest Social Security Office with their passport, DS-2019 form  and an the Employer Letter (which we will send you). However you will get more detailed information on the steps to doing it right before going to the U.S. in the Pre-Departure Orientation Session by Architect-US and ASSE.
