Why do some people choose DTV over METV for staying in Thailand?

They're totally different visas: different requirements, different length, different price, etc.

What is the difference between a holiday, meaning no working and enjoy a new culture

and working, meaning sitting hours behind a computer to gain income.

The METV is ideal for those wishing a stay of up to 180 days. The requirements are quite simple and obtainable. If one is looking for a friction-free visa allowing them to travel the region while based in Thailand it's ideal. I come to Thailand for 4-5 months annually and it suits me perfectly.

METV is a 6 month visa that you have to depart every 90 days..you can get a total of 9 months out of it with a strategic last 2 day visa run

DTV is a 5 year visa where you have to depart country every 6 months

You can get extensions on both visas in country but it’s just way easier to do a border bounce, border run, microcation, minication or long vacation to reset the visa for its next duration of time

People usually opt for the DTV due to the longevity of the visa

The 5 year Elite visa costs more but you get way more benefits in country like opening a bank acct and once per year departure

Good Luck
