Thailand visa extension — a complete file before you queue
Retirement, marriage, business or tourist — we prepare the documents, translations and TM30 check so your extension of stay is filed right the first time.
How extensions work
An extension of stay is granted by Immigration on top of your visa or entry stamp. Each category has its own evidence — financial, family or employment — and local offices differ in what they ask for. Most delays come from a missing TM30, an untranslated foreign document or a bank letter in the wrong format.

Frequently asked questions
Which visas can be extended in Thailand?
Tourist entries can usually be extended once at Immigration, while non-immigrant visas such as retirement (O/O-A), marriage (O), business (B) and education (ED) can be extended for up to a year when the conditions are met.
When should I apply?
Many offices accept applications up to 30 days before your permission to stay ends. Practice varies by office, so we confirm the timing with your local office.
What documents are usually needed?
Passport copies, form TM7, photos, the TM30 receipt for your address and category documents — bank letters for retirement, marriage certificates and photos for marriage, or company papers and a work permit for business.
Do foreign documents need translation?
Usually yes. Foreign marriage or birth certificates and income letters often need certified Thai translation and legalisation. We handle this in-house.
What if my extension is refused?
You are typically given a short period to leave Thailand. We review the reason, correct the file and advise on the best next step before your stay runs out.
How much does it cost?
Our service fee is quoted per case. The government fee is paid at the official rate.
