Use the following checkpoints to compare your real options before signing contracts, buying insurance or applying for a visa.
Confirm your exact category
Check non-immigrant O, O-A and any longer-term options against the Thai embassy or consulate serving your residence. Age and eligibility requirements depend on the category.
Budget beyond the visa
Account for insurance, medical out-of-pocket costs, exchange-rate movements, renewal administration and access to healthcare in your intended city.
Avoid informal promises
Do not rely on an agent's guaranteed-approval claim. Ask what official application route and document list will be used and verify details before paying fees.
