Bangkok, 17 October 2024 – Thailand has extended the suspension of the requirement to fill out the ‘To Mo 6’ (TM6) immigration form for foreign travellers entering and exiting Thailand at 16 land and sea checkpoints until 30 April 2025.
The TM6 form is the arrival/departure card, which foreigners are required to fill out with their passport information and other personal and travel information when entering or leaving Thailand. The form was permanently cancelled for foreign travellers arriving by air since July 2022.
