Can American applicants file the Visa Extension themselves?

Yes, self-filing is possible. Most American clients still engage professionals because (1) source-country documents require lengthy translation and legalisation, (2) Immigration 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 United States take 2–4 weeks, then Thai filing at Immigration takes 1–7 business days.

What is the total cost?

Government fees are charged at the official government rate, plus our service fee confirmed in a written quotation depending on complexity, plus foreign-document legalisation fees confirmed after document review depending on volume.

What changes for United States documents after 28 Feb 2027?

If United States is a Hague member, its documents receive Apostille instead of full legalisation — saving 5–15 business days and the fee that would otherwise be confirmed in a written quotation.

Can family members follow?

Yes. The Visa Extension 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).

Do visa supporting documents have to be translated?

If the document is not in the language the authority accepts, yes. Australian and UK authorities generally require a full translation by a qualified translator with a signed certificate; Schengen missions in Bangkok usually require Thai documents to be translated into English or the destination language and legalised by the Department of Consular Affairs first.

Can you guarantee my visa will be approved?

No, and any provider who guarantees an outcome should be treated with caution. Immigration officers decide on the evidence and applicable law. Our role is to make sure the evidence is complete, consistent across documents, correctly translated and certified in the format the authority expects.

What is TM30 and who has to file it?

TM30 is the notification of a foreign national's place of residence, filed by the owner, possessor or manager of the property where the foreigner stays. It is separate from the 90-day notification made by the foreign national. Missing filings can create problems at extension or re-entry, so they are worth checking before an application.
