When you need your U.S. documents accepted in Thailand, the process is different from most other countries. Thailand is not a member of the Hague Apostille Convention, which means you’ll need to go through a multi-step embassy legalization process — not just an apostille.

At Orange County Apostille, we specialize in Thailand document legalization — helping individuals, families, and businesses in Irvine, Costa Mesa, Buena Park, and all across Orange County get their paperwork accepted abroad quickly and correctly.

✅ What’s the Difference Between Apostille and Legalization for Thailand?

Countries that signed the Hague Apostille Convention accept a single apostille certificate.
Since Thailand has not joined the Hague Convention, documents must be authenticated through:

The California Secretary of State
The U.S. Department of State
The Royal Thai Embassy or Consulate

Our team ensures your documents meet all the California Secretary of State apostille requirements and are properly presented for Thai Embassy legalization.

🗂️ Step-by-Step: Thailand Embassy Legalization Process

Step 1 – Document Review & Notarization

We verify that your documents are ready for submission — properly notarized or certified.
If you need help notarizing, we can refer you to Your Local Notary for professional mobile notary service anywhere in Orange County.

Step 2 – State Authentication

Your notarized document is authenticated by the California Secretary of State in Sacramento or Los Angeles.
If you’re located near Mission Viejo or Fountain Valley, we can also arrange pickup and drop-off to save you time.

Step 3 – Federal Authentication

Documents requiring federal validation (such as FBI background checks) are authenticated through the U.S. Department of State – Office of Authentications in Washington, D.C.

Step 4 – Thai Embassy or Consulate Legalization

Finally, your document is submitted to the Royal Thai Embassy in Washington, D.C. or Royal Thai Consulate in Los Angeles for legalization.

Once approved, your document becomes legally recognized in Thailand — whether for visa processing, marriage registration, or business incorporation.
