Process for Visa Extension on a Non-ED Visa for Children in Thailand

The process for extending a Non-ED visa for children follows the standard Thai immigration extension steps with extra parental documents and financial proof depending on the exact visa type. Thai Kru Visa Agency manages document checking, prepares everything, and sends a team to accompany families at the immigration office so the day runs smoothly.

The Specifics

• Service fee is 12,000 Baht per child. This includes the immigration fee.
• Parents must bring their own documents in advance because officers often request them.
• TM30 arrival/residence reports are required for the child and both parents; these are used to complete the address section of the extension form.
• A rental agreement in Thailand is mandatory. It must be signed and include a Certified True Copy of the lessor’s ID card (page 13) plus the lessor’s signature on the agreement itself.
• Clear scans of every passport page that contains immigration stamps are needed. Both pages of any double-page spread must be scanned together.
• Two physical 4x6 cm photos are required on the extension day.
• If the child’s visa is linked to a guardian Non-O or similar visa, a Thai bank account showing 500,000 Baht held for at least 3 months is usually required. On the day you also bring the bank certificate of balance, the past 1-year stamped transaction statement, and the bank book.
• Any existing passport stamp can be transferred directly by the immigration officer during the extension process.
• A multiple re-entry permit can be added the same day; the agency assists at no extra service charge (you pay the government fee directly).

Expert Tips from Thai Kru Visa Agency

Start early. Send us clear passport scans and the rental agreement so we can check everything before the expiry date. We aim to arrive at immigration with the first queue numbers, keeping the visit to roughly 1–2 hours.

Keep parents’ passports, TM30s, and marriage or birth documents ready. Officers frequently ask for them even when the application is only for the child.

For bank-related visas, make sure the required balance has been sitting in the Thai account for the exact period stated (2 or 3 months depending on visa category). We double-check the stamped statements so nothing is rejected on the day.

If you also need to understand the ED visa extension process for children or want the general visa extension process in Thailand, those guides sit alongside this one.
