Thailand has allowed foreigners to enter the country under the Visa Exemption program for 45 days (15 days in a state quarantine) via an international airport and a land border checkpoint from neighboring countries.
The visa exemption rule allows tourists from 64 countries to enter Thailand without a visa. It will also be necessary to prove that you have funds of at least 10,000 baht per person or 20,000 baht/family during your stay in Thailand.
