What type of visa should I apply for if I want to stay in Thailand for 6 months without buying a year of health insurance?

It seems like we're just going round and round with the O/P not wanting to carry a year of both covid insurance and the mandatory 40k/400k out/in-patient health insurance for the O-A visa because they're only going to be here for 6 months.

Seeing as you get stamped in for the validity of the insurance(s) if you only wanna be here 6 months then the answer is get just 6 months of the insurance(s). When you apply for the COE show that you are leaving before the insurance expires AND when you arrive you'll get stamped in as long as your insurance is valid for.

Hans, between what James and Benjamin have advised you have your solution. As you have no ties here in Thailand you may wish to travel. On a tourist visa is the easiest way forward for you to stay here. If you decide to stay here on a OA visa and extension you have other issues with which immigration office you use for reporting and being approved extensions of stay. Come here first and see how it fits with you. Take the advice. - Get the Tourist Visa and whatever is required for your intended length of holiday. The Thai embassy in your country will tell you exactly what you need before they issue a tourist visa, and is hands-down the easiest way for you.

Please stop using the fancy graphics... Use simple English type on facebook. Much easier to read your post. I cannot scroll down to read your post on my phone.

Thank you.

JUST A REMINDER: The absolutely terrible designed Special Tourist Visas are no longer being sold. Thank you.

Get a single entry tourist visa from the thai consulate in the country you're in. Come here, get stamped in for 60 days, take the 30 day regular extension for 1900baht at the immigration office and during that 90 days you're allowed here look for other longer term visa/extension options.

That choice only requires you to have 60 days of the 100K USD covid insurance.

As well as the Covid insurance if you come on an OA visa bought in your own country you also need general medical insurance as well as the Covid cover. If your medical insurance is only valid for 6 months then you will only get stamped in for 6 months, so the duration of the insurance doesn't need to match the duration of the visa

Sadly, there is no "six month visa". But, what do you mean by "income settled"? Do you have the 800K THB in a savings account/ 65K THB a month in monthly income from a pension?
