Why use counsel for Thai Citizenship

Small errors (order, mistranslation, missing stamp) cause rejections. Our 3-step internal checklist catches them before submission.

We file Thai Citizenship at the Japan Embassy continuously and know where Visa Officers focus and which flags need a pre-emptive cover letter.

Send documents via LINE/email. We review within 24 hours, return comments, then schedule notary and the rest of the chain.

Documents required for the Japan Embassy

Thai-issued documents should be notarised and MFA-legalised before submission, so the Japan Embassy accepts them on first pass.

Foreign documents may need Apostille or full legalisation depending on whether Japan is an Apostille party — we verify upfront.

Fees and timeline

Reference processing time for Thai Citizenship is around 24–60 เดือน days; we recommend starting at least 4-6 weeks before the travel date.

In-depth Questions Clients Ask Most

These are the most frequent questions clients in Bangkok ask before booking Visa & Embassy Service. Each answer is reviewed quarterly by our editorial team against current Lawyers Council, MFA, and embassy guidance, so the dates, fees, and process windows on this page stay accurate.

How long does Visa & Embassy Service typically take for clients in Bangkok?
Standard turnaround is 1–2 business days for the notary stage, plus 2–3 days at the Ministry of Foreign Affairs and 1–7 days at the destination embassy depending on the mission. Express handling can compress the full chain into 24–48 hours for clients with a verified visa appointment or court hearing.
Can the documents be used outside Thailand without further legalisation?
Documents notarised in Thailand are accepted abroad only after the chain — Notary → MFA → Embassy or Apostille — is complete for the destination country. Since Thailand's Hague Apostille membership took effect on 14 February 2026, a single Apostille now replaces embassy legalisation for member states such as the US, UK, Japan, Korea, Germany, France, Australia, and 100+ others.
What identification documents must I bring to the appointment?
For Thai nationals: national ID card plus the original document. For foreigners: passport plus a valid Thai visa or entry stamp. Corporate clients should bring the company affidavit (DBD), the authorised signatory's ID, and the company seal if used in the document.
Do you provide certified translations alongside the notary service?
Yes. NAATI-credentialed translators (English, Chinese, Japanese, Korean, German, French, Spanish, Arabic) work in-house, so the translated version can be notarised the same day. This avoids the common delay of bouncing between a translation vendor and a notary office.
What is your refund or rebooking policy?
If the document is rejected by the MFA or destination embassy due to an error on our side, we re-process at no charge and refund all MFA / embassy fees. If the rejection is due to client-provided information (e.g. spelling or missing supporting documents), we offer a 50% rebooking discount.

Pre-Submission Compliance Checklist (12-Point)

Before we file your Visa & Embassy Service with the MFA or any embassy, every case passes a 12-point checklist. This is the same checklist used internally by our senior counsel during the final QA step.

  5. 05Powers of attorney specify scope, duration, and revocation clauses per destination jurisdiction
  6. 06Educational transcripts bear original university seal, not photocopy
  7. 07Medical certificates include licensed physician registration number (per MFA rule 2021)
