After a Cabinet meeting last week, Prime Minister Prayut Chan-o-cha announced the Thai Government will temporarily suspend the TM6 immigration card for arriving passengers to help ease congestion, screening, and processing times at international airports. The proposal will be implemented within 7-10 days, but it is clearly stated that the change is only temporary while Thai Immigration assesses the flow-on effects.
The TM6 card is one of the major requirements for foreigners to apply for a visa extension at the immigration office, so if you have plans to extend your visa or change your visa, it is recommended that you fill out the TM6 card on arrival even if it is currently suspended.”
