Certificate of Naturalization

The U.S. Department of State – Office of Authentications in Washington, D.C. is the only authority that can issue an apostille for a Certificate of Naturalization. This is because the document is federal in nature and cannot be authenticated at the state level. At Orange County Apostille, we work with a D.C.-based team to streamline the submission process and ensure your documents meet all requirements. Our services include full tracking, federal fee payment, and secure return shipping. Visit the U.S. Department of State’s website to learn more about federal apostille jurisdiction.

The processing time for a federal apostille is typically 10 business days, depending on the volume of requests at the U.S. Department of State. At Orange County Apostille, we provide expedited service options through our Washington, D.C. office, minimizing delays and ensuring secure handling of your documents. We notify you once your apostille is issued and arrange for delivery back to your chosen address. You can learn more on our Federal Apostille Services page.

Countries that are members of the Hague Apostille Convention will require your Certificate of Naturalization to be apostilled before it can be used abroad. This includes countries like Mexico, Italy, Spain, Germany, Argentina, Poland, and Brazil. For a complete list of member countries, visit the HCCH official site. If the destination country is not a Hague member (e.g., China, UAE, or Egypt), you’ll need to go through embassy or consular legalization instead. Orange County Apostille can assist with both processes.

If your Certificate of Naturalization is being submitted to a non-Hague country (e.g., China, Saudi Arabia, Vietnam, UAE), it must go through a more complex process called embassy or consulate legalization. This includes notarization, state-level authentication (if required), U.S. Department of State certification, and finally embassy legalization. Orange County Apostille manages the full chain of custody, translations, and embassy submissions for such cases. Learn more about non-Hague legalization services.

If the destination country does not accept English-language documents, you will need a certified translation of your Certificate of Naturalization. At Orange County Apostille, we offer certified translations in over 90 languages, all of which meet international standards and embassy requirements. Each translation includes a certificate of accuracy to ensure acceptance. You can learn more about this service on our Translation Services page.
