Which of the following documents can establish both identity and employment eligibility under the Immigration and Nationality Act?

The U.S. passport is a powerful document that serves as both proof of identity and employment eligibility under the Immigration and Nationality Act. It is issued by the federal government and includes a photograph of the holder, which helps to verify identity. Furthermore, a U.S. passport confirms that the individual is a citizen of the United States, which satisfies the requirements for employment eligibility as per federal regulations.

Other documents, while they may establish identity, do not fulfill both requirements as effectively. For instance, a driver's license is primarily a form of identification and signifies the capability to drive, but it does not guarantee citizenship status. A Social Security card confirms the individual’s eligibility to work but does not serve as a primary identification document. A birth certificate establishes identity and can indicate citizenship, but it does not function as a photo ID, which can be necessary for certain verification processes.
