What is the process like upon landing in Thailand for travelers under quarantine?

After landing in Thailand, travelers can expect a highly organized immigration process. They will first walk to the immigration counter where they need to present various documents such as a visa, Certificate of Entry (COE), reservation for Alternative State Quarantine (ASQ), and possibly a COVID-19 test result. The immigration experience is described as smooth and controlled, akin to a production line, with travelers being guided throughout the process. It is advisable to have multiple copies of all necessary paperwork on hand. After completing immigration and collecting luggage, travelers are directed to transportation that will take them to their ASQ accommodation.
