The SSN appears on social security cards, tax returns, or bank statements. You need one to work in the United States.
The Social Security Number (SNN) is a nine-digit number that US citizens receive for tax purposes. However, permanent residents and holders of a non-immigrant work visa can also obtain it.
Beneficiaries of DACA (Deferred Action for Childhood Arrivals), can apply for an SSN through a form I-765. Consult more information about this procedure at the following link: https://citizenpath.com/faq/social-security-number-form-i-765/
However, DACA recipients who have authorization to work issued by the United States Citizenship and Immigration Services (USCIS) can apply to obtain an SSN. Through the SSN it is possible to collect Social Security benefits and apply for other government services.
On the other hand, it is important to bear in mind that, to obtain a driver's license, enroll in a school, take out private health insurance, among others, it is not always necessary to have an SSN.
