How Thai Americans Can Claim Their Thai Citizenship: Step-by-Step Guide to Getting a Thai ID and Passport

Sawadee khrup. It’s Monchai again.

Are you a Thai American wondering how to claim your Thai citizenship and get a Thai ID card and Thai passport? My friend Amy, born and raised in Phoenix, Arizona, recently began the journey to officially reclaim her Thai nationality by descent, which would allow her to have more flexibility as a dual citizen. We documented the entire process — and this guide is for you if you’re ready to do the same.

🧬 Who Qualifies for Thai Citizenship by Descent?

If you were born abroad and at least one of your parents was a Thai citizen at the time of your birth, you’re likely already a Thai citizen by law — you just need to register and claim it officially.

✅ Step-by-Step Guide to Claiming Thai Citizenship for Thai Americans

1. Confirm Thai Parentage and Citizenship

Start by confirming that at least one parent held Thai citizenship when you were born.

Required documents:

• Thai national ID card (บัตรประชาชน)

• Thai passport

• Thai house registration book (ทะเบียนบ้าน)

📌 Tip: Both parents having Thai citizenship makes the process smoother, but only one is legally required.

2. Register Your Birth with the Thai Government

Check if your Thai birth registration was completed at a Thai embassy or consulate when you were born.

If not, do this ASAP.
Amy needed to register her birth retroactively with the Royal Thai Consulate in Los Angeles.

What you’ll need:

• U.S. birth certificate (original + Thai translation)

• Parents’ Thai citizenship documents

• Parents’ marriage certificate (original + Thai translation)

• Childhood family photos (optional but very helpful)

📌 End goal: A Thai birth certificate will be issued, which is essential for the next steps.

3. Register in a Thai House Registration Book (Tabien Baan)

Once your Thai birth is recognized, you need to be listed in a Thai household registry (ทะเบียนบ้าน). Amy chose her family home in Chiang Mai.

What to do:

• Pick a Thai address (parent’s or relative’s)

• Visit the local district office (amphoe or khet)

• Submit documents and request to add your name

📌 Note: You don’t gain property rights by being listed — just proof of Thai residency.

4. Apply for Your Thai ID Card (บัตรประชาชน)

After being registered in the household, head to the local government office to apply for your first Thai national ID.

Required documents:

• Thai house registration with your name listed

• Thai birth certificate or translated U.S. birth certificate

• U.S. passport

• 2 passport-style photos

• Thai-speaking parent or relative (highly recommended)

📌 Important: This must be done in person in Thailand. No remote applications are allowed.

5. Apply for a Thai Passport

With your new Thai ID card, you can now apply for a Thai passport, either in Thailand or at a Thai consulate in the U.S.

Cost in Thailand:

• 5-year passport: 1,500 Baht

• 10-year passport: 2,000 Baht

• Expedited service: Available for an extra fee

Documents required:

• Thai ID card

• Thai house registration book

• U.S. passport

• Optional: 2 passport-style photos (passport office may take one on-site themselves)

📌 Thai passport offices in Thailand usually take your photo digitally on the spot, plus bio-metrics.
