What is the primary difference between using a U.S. passport and a driver's license for I-9 verification?

The primary difference in using a U.S. passport compared to a driver's license for I-9 verification lies in the scope of what each document establishes in terms of identity and work authorization. A U.S. passport serves as a comprehensive form of documentation that confirms both the identity of the individual and their citizenship, thereby providing evidence of work authorization under federal law.

In contrast, a driver's license typically verifies identity but does not inherently provide proof of work authorization unless accompanied by specific supplemental documentation that confirms the individual’s eligibility to work in the U.S. Therefore, the U.S. passport can be used alone for I-9 verification to fulfill both criteria effectively, while the driver's license may not suffice for establishing the legal right to employment without additional documentation.

This distinction is crucial in I-9 verification processes, emphasizing the strength of a passport as a singular document that covers both identification and work eligibility, which is essential for compliance with employment regulations.
