Retirees typically follow one of two routes: the Non-Immigrant O-A, applied for at a Thai embassy before travel and requiring Thai-compliant health insurance, or a Non-Immigrant O obtained in Thailand and then extended annually on the basis of retirement.
Annual extensions are granted by the local immigration office for your province, and documentary practice varies between offices. We prepare files to the standard of the office that has jurisdiction over your address.
What we handle
- Choice between O-A (embassy) and O-to-extension (in-country) routes.
- Deposit seasoning and bank-letter preparation under current immigration rules.
- Pension income evidence via embassy letters or affidavits where accepted.
- Health insurance coordination for O-A applicants.
- Annual renewal, 90-day reporting and re-entry permit management.

Why are applications refused, and how do we prepare?
| Common refusal reason | How we prepare |
|---|---|
| Funds not seasoned in a Thai account for the required period | We plan the deposit timeline months ahead. |
| Income letter or pension proof not accepted by the local office | We prepare the evidence the specific office accepts. |
Counsel's note
Deposit requirements include seasoning periods before and after each extension. Withdrawing funds too early is a common reason for refusal at renewal.
