Sorry, but the general requirement is also be age 50 years unless youāre married to a Thai. There are some options anyway.
A multiple entries tourist visa can give you up to nine months in Thailand.
If you like MuY Thai, attending a course could also give you a visa for a period.
If you want to study or learn Thai you can get a one year ED visa.
Thereās a privilege visa which gives you from five years if you can and are willing to pay.
Some people do border and visa runs for a period, but this is not an easy way to spend time in Thailand after a while.
