Can Korean applicants file the Thai Citizenship themselves?

Yes, self-filing is possible. Most Korean clients still engage professionals because (1) source-country documents require lengthy translation and legalisation, (2) กระทรวงมหาดไทย operates primarily in Thai, and (3) missing documents force restarts that cost far more time than the service fee.

What is the total timeline?

Roughly 4–8 weeks: translation and legalisation from South Korea take 2–4 weeks, then Thai filing at กระทรวงมหาดไทย takes 24–60 เดือน business days.

What is the total cost?

Government fees quoted after document review + NYC Legal service fee quoted after document review depending on complexity + foreign-document legalisation quoted after document review depending on volume.

What changes for South Korea documents after 28 Feb 2027?

If South Korea is a Hague member, its documents receive Apostille instead of full legalisation — saving 5–15 business days and Fee quoted per document before work starts.

Can family members follow?

Yes. The Thai Citizenship typically grants Non-O Dependent status for spouse and children under 20, renewable together with the principal visa.

Can I work in Thailand on this visa?

Yes — with a Work Permit filed at the Ministry of Labour (some visas such as LTR and Smart Visa do not require a separate WP).

My document type is not listed. Can you still help?

Usually yes. Send the document and the instruction from the authority that requested it. The chain of certification depends on who issued the document and who will receive it, not on a fixed catalogue, so unusual documents are assessed individually before a plan and a fee are proposed.

Do you handle electronic documents and e-signatures?

Where the receiving authority accepts them, yes. Thailand recognises electronic signatures under its electronic transactions legislation, but many foreign registries and embassies still require a wet-ink original with physical seals. The accepted format should be confirmed in writing before work begins.

What if the destination changes its requirements mid-process?

We re-check requirements close to the filing date for exactly that reason, and if they change we set out the revised steps and any additional cost before continuing. Documents already certified can often be reused in the new chain, which limits the impact.
