Arrival card and permission to enter
Submit TDAC free of charge at tdac.immigration.go.th within the three-day window including arrival day. It is separate from a visa and the border decision. A new entry needs a new card, including for children; airside transit is a separate case. Before buying tickets, verify the current entry regime for each traveller’s nationality and passport type.
Russian ordinary passports: the current check
The official government publication of 2 September 2026 and its MFA infographic state a revised regime effective 15 September 2026: Russia is listed in the bilateral 30-day exemption group for ordinary passports. Do not rely on the former general “60 days for Russians” statement. Recheck the rule for your trip and then the actual permitted-stay endorsement.
Errors, confirmation and intermediaries
Match the passport spelling, flight and actual accommodation address, then save the confirmation offline. The official instructions allow a corrected new submission where a protected field cannot be edited. A private service charge is not a government TDAC fee. Check the domain before sending passport data, even when a search advert appears first.
Next steps
- Check the entry regime for each passport.
- Open official TDAC and prepare the address, flight and passport.
- Review every child’s and adult’s details.
- Save the QR confirmation and check the permitted-stay date after entry.
