Do interns and trainees have Social Security numbers?
A. If interns or trainees have previously participated in the J-1 Work & Travel, Camp, or H-2B programs, they will have a Social Security number and card already. If this is their first time working in the US, they must apply at your local office for a card. They will receive a receipt that shows that they have applied for a Social Security card, which should arrive within 6 weeks.
