What Documents Are Required for a Visa Application Generally?

Visa applications generally require a valid passport, recent photos, proof of funds, a completed application form with barcode (such as DS-160), travel plans, and supporting documents like a birth certificate. The exact list always depends on the visa type, your nationality, and where you are applying.

The Specifics

• Current valid passport – biodata page must be clear.
• Visa photographs – standard 2x2 inches; for some Thai extensions, 4x6 cm photos are needed, especially for children.
• Proof of payment and appointment confirmation.
• DS-160 confirmation page with barcode (required for many US visa applications).
• Lease agreement or accommodation details.
• Travel itinerary or plan.
• Bank statements – often showing activity for 3 to 12 months and sufficient funds.
• Birth certificate – must be clear, readable, and sometimes translated.

Financial thresholds change by visa. A Non-O Retirement Visa may need 800,000 Baht in a Thai bank for 3 months (or 2 months for extension), while a DTV Visa requires 500,000 Baht (or equivalent) in your name for the last 3 months. A Marriage Visa extension typically needs 400,000 Baht in a Thai account for at least 2 months on the extension date.

If converting a visa inside Thailand, a local Thai bank account is required to deposit and show the necessary funds. Documents that are not in English usually need certified translations.

Expert Tips from Thai Kru Visa Agency

Always tell us your nationality and current location first. This lets us give you the precise checklist instead of a general one. For retirement or marriage extensions we often accompany you to immigration. Bank statements must be recent and show consistent activity; unclear birth certificates cause delays.
