아 그렇군요. 근데 F2 비자의 경우 SSN을 발급 받을 수가 없습니다.

How do I apply for a Social Security number and card?

Unless you are a noncitizen who wants to work in the United States, you probably do not need a Social Security number.

Generally, only noncitizens authorized to work in the United States by the Department of Homeland Security (DHS) can get a Social Security number. Social Security numbers are used to report an individual’s wages to the government and to determine a person’s eligibility for Social Security benefits. You need a Social Security number to work, collect Social Security benefits and receive some other government services.

Lawfully admitted noncitizens can get many benefits and services without a Social Security number. You do not need a number to get a driver’s license, register for school, obtain private health insurance, or to apply for school lunch programs or subsidized housing.

Some organizations use Social Security numbers to identify you in their records. Most, however, will identify you by some other means if you request it.

We cannot assign you a Social Security number solely so you can get a driver’s license or a service that requires a credit check.

Although many companies, such as banks and credit companies, may ask for your Social Security number, you are generally not required to provide one if you don’t have one.
