The Specifics

• Thai bank account balance of THB 500,000 held for a minimum of two months on the date of your visa extension application.
• Last three months of Thai bank statements.
• Bank certificate confirming the balance and duration of funds.
• Evidence of the source of the funds.
• Passport with current Thailand entry stamp.
• TM.30 Residence Notification form.
• Physical 2-inch photograph of the child (the student).
• The child and their passport must attend the appointment.
• Supporting document requested by the relevant Embassy.

Expert Tips from Thai Kru Visa Agency

A US or overseas bank account is not accepted for this visa type. The funds must sit in a Thai bank account. If you combine two Thai accounts to reach the 500,000 baht requirement, approval remains at the immigration officer’s discretion.

Always bring the original bank certificate together with the three-month statements. Officers routinely check both the ending balance and how long the money has been present.

Read our guide on why an overseas bank account will not satisfy Thai visa financial rules. Families whose child studies at an international school in Thailand should also review the full Guardian visa process before the extension appointment.

Thai Kru Visa Agency does not offer a financial-proof service. We focus on preparing and submitting the complete visa-extension file. Our team stays with you until the extension is approved, sometimes meeting at the immigration office.
