🇨🇭 Switzerland · Thai Naturalisation (Citizenship)
We prepare the complete criminal-record packet a Switzerland national needs to file Thai Naturalisation (Citizenship) in Thailand. Every step — from the fingerprint appointment at the Royal Thai Police Criminal Records Division to the sealed Apostille packet accepted by Special Branch Bureau → Ministry of Interior → Royal Command — is managed by one case attorney.
Naturalisation as a Thai citizen under Nationality Act. Under Nationality Act B.E. 2508 (as amended) §10–12, Special Branch Bureau → Ministry of Interior → Royal Command requires evidence that the applicant has no disqualifying criminal history — both in Thailand (where the applicant currently resides) and, for Switzerland nationals, in the country of nationality. The certificate must be current (issued within 90 days of filing for most desks; 60 days for BOI/Immigration). For Switzerland applicants this typically means combining a Thai RTP-1 with a Strafregisterauszug (Federal Office of Justice) certificate; both must be translated (Thai + English) and legalised.
The specific requirement stack for Thai Naturalisation (Citizenship) makes this filing more complex than a generic tourist-visa criminal check. Special Branch Bureau → Ministry of Interior → Royal Command refuses packets missing any of: (a) the correct receiving-authority cover form; (b) certified translation in the accepted language pair for Switzerland documents (TH → PLUS-EN); (c) the legalisation chain required by bidirectional — thai mfa/apostille + home-country apostille/consular. We build every packet to survive first-pass acceptance.
You will attend the Royal Thai Police Criminal Records Division (Muang Thong Thani) with passport, TM.30 residence proof and current visa. As a Switzerland national ordinarily resident in Thailand you qualify for RTP-1 issuance after 6 months of continuous residence. We schedule the fingerprint appointment, prepare the TR-16 form, and collect the certificate on the 5th business day.
We liaise directly with Strafregisterauszug (Federal Office of Justice) using the Online request → PDF → Federal Chancellery Apostille → courier channel. Typical turnaround is 12–20 business days. For Thai Naturalisation (Citizenship) filings we prepare the request cover letter in the format the receiving authority accepts, and courier the sealed envelope back to Thailand.
A Thai + English bilingual certified translation is prepared, matched to the receiving authority's template for Thai Naturalisation (Citizenship).
Thailand acceded to the 1961 Hague Apostille Convention on 30 June 2026; it enters into force for Thailand on 28 February 2027, so Apostilles are not yet issued. Thai documents are legalised at the Department of Consular Affairs, Ministry of Foreign Affairs, and then at the destination country mission where that country requires it.
Naturalisation as a Thai citizen under Nationality Act. Legal basis: Nationality Act B.E. 2508 (as amended) §10–12. We submit the packet to the correct desk, obtain the acceptance receipt and monitor case status until issuance of the underlying document (Thai Naturalisation (Citizenship)).
Where required for onward use overseas (particularly for Switzerland home-country filings), our Notarial Services Attorney (Lawyers Council of Thailand, Lic. No. 1851/2557) applies the notarial seal and signature to the sealed packet, satisfying the "notarised copy" requirement of most third-country immigration authorities.
Single case manager end-to-end. You receive a shared case folder, courier tracking, weekly status update and a compliance audit trail suitable for tribunal or immigration review. Deadline compliance is guaranteed within our stated 25–45-day SLA.
Home authority: Strafregisterauszug (Federal Office of Justice).
Ordering route: Online request → PDF → Federal Chancellery Apostille → courier.
Typical home-country turnaround: 12–20 business days.
Legalisation of the home certificate: Apostille (Hague Convention).

From fingerprint appointment to sealed certificate: 5 business days. Full end-to-end packet (RTP-1 + translation + legalisation) for Thai Naturalisation (Citizenship): 25–45 business days. We manage the appointment, translation and legalisation as a single workflow.
Yes — but only when it carries the correct legalisation. For Switzerland nationals we obtain the certificate via Strafregisterauszug (Federal Office of Justice) using the Online request → PDF → Federal Chancellery Apostille → courier channel, then apply the home-country Apostille and a certified Thai translation.
Packages start from ฿28,000 and include government fees, translation, legalisation and courier. Optional add-ons (embassy authentication, notarisation) are quoted separately after the case review.
Yes. We accept a signed power of attorney (POA) — for Switzerland nationals we provide a bilingual POA template that satisfies both Thai RTP fingerprint requirements and Strafregisterauszug (Federal Office of Justice) ID verification.
We check every certificate against the receiving-authority template on receipt. If Strafregisterauszug (Federal Office of Justice) issues a document with a misspelt name, wrong date of birth or missing signature, we open a correction request the same day at no additional professional fee — you only cover the reissue government fee.
