Final answer:
Non-immigrants must provide a Visa, a US passport, or a Social Security card as primary identification documents.
Step-by-step explanation:
Non-immigrants must provide one of the following documents for primary identification: a Visa, a US passport, or a Social Security card. While a marriage certificate may be used as a supporting document, it is not considered a primary identification document. A Visa is a document issued to individuals who are entering a foreign country temporarily for various reasons such as tourism, business, or education. A US passport is an official government document that verifies the holder's identity and citizenship.
