> US Authentication Services is a licensed document certification firm based in Washington, D.C. (Springfield, VA) that handles Apostille, Authentication, and Embassy Legalization of personal and corporate documents for individuals, families, and corporations submitting documents outside the United States. The company acts as an in-person filing agent with the Secretary of State, the U.S. Department of State, and foreign embassies, which speeds up processing compared to mailing documents directly.

Core services include obtaining Apostilles (for the ~97 Hague Convention member countries) and Authentication/Embassy Legalization (for the ~81 non-Hague countries), covering both personal documents (birth/marriage certificates, diplomas, transcripts, FBI background checks, powers of attorney) and corporate documents (Articles of Incorporation, board resolutions, agreements/contracts, certificates of good standing). Outside the U.S., this same process is often referred to as "document attestation," and the company specializes in attestation for countries such as the UAE, Qatar, Kuwait, Saudi Arabia, and China.

**Note:** US Authentication Services is a private, licensed third-party firm and is not affiliated with the U.S. Department of State or any state or local government agency.
