Travelers are required to contact the Royal Thai Embassy or consulate to get an entry visa and a certificate of entry, which will be considered on a case-by-case basis, taking into account the urgency, said CCSA in a statement.
Applications for inbound travelers must include travel details, health insurance with a coverage of at least US$100,000, as well as booking at an alternative state quarantine site.
Once the inbound traveler lands in Thai soil, he or she will need to demonstrate to airport and health authorities a certificate of a COVID-19 test taken within a 72-hour period with a negative result and a fit-to-fly certificate.
However, to ensure that the traveler carries no symptom of COVID-19, he or she will need to undergo another COVID-19 test at a Thai airport, and then be transferred to an alternative state quarantine site that should have been booked in advance.
The CCSA said that the groups of foreigners allowed into Thailand may include spouses, parents or children of Thai nationals; non-Thais with rightful papers to work in Thailand, or on student visa, and tourists who had already made appointments with Thai hospital for medical treatments.
The CCSA reiterated that all inbound travelers must go through 14-day mandatory quarantine under their own expenses.
For those on very short trips to Thailand including filmmakers and business people participating in trade fairs, they will have to stick to their itineraries and will not be allowed to wander to public venues or take public transport.
These people are exempt from the 14-day mandatory quarantine procedures.
The CCSA said that every application to enter into Thailand, will be reviewed case by case.
It said Thailand had already entered into a two-month period free of COVID-19 local transmission and will do anything to avoid a second wave of COVID-19 infections.
