This recent article below reflecting the viewpoint of a senior Thai Immigration Official paints a dismal picture of foreigners coming to Thailand after July 1 in numbers beyond a few hundred returning Work Permit holders and Spouses of Thai citizens, Diplomats and other odds and ends people who want to deal with the obstacles. It seems the Covid-19 Health Certificate with Negative Test will remain along with the $100,000 Covid Health Insurance. This isn't a big surprise. But the discussion here of a Vaccine having to be available before a return to normality is daunting as a release date of any Vaccine is anybody's guess. Please read and provide feedback.
And for those of you who want to attack me - the messenger - then Don't.
TLDR : Answer Summary
A recent article indicates that foreigners, with the exception of a few specific categories, face significant obstacles in returning to Thailand after July 1, 2020. The Thai Immigration officials have maintained the requirement for a COVID-19 health certificate and a minimum of $100,000 in health insurance for entry. There are concerns about the delay in vaccine availability affecting the likelihood of returning to 'normal' travel and tourism levels. Many commenters express frustration over the situation, highlighting the severe impacts on Thailand's economy, particularly in tourism-dependant regions.
