Is there a visa that allows a 6-month stay in Thailand?

Anthony van der Craats the country of passport makes no difference as far as various visas. It only makes a difference for whether one qualifies for visa exempt entry, which won't give the OP what they want regardless of nationality. The OP is asking a question that many people in this group know enough to answer. There's no point telling someone to ask the embassy, as that would make the group completely useless since you could give that same reply for all visa and entry related questions. Since this is a visa advice group, the OP is obviously seeking advice from knowledgeable group members, not just to be told to ask the embassy.

I get 90 day stay per visit, (Limit is two stays per calendar year it resets on Jan 1). Most countries get 69 days stays. I hold an ABTC APEC Card) The DTV might be your best option. Really depends on what and when you plan to stay. Talk to the Thai Embassy in your county.

Yes we got 30 days for second extension but many others got only 7 days…so depend of the immigration agent 🤷‍♀️

But next year, will take OA visa, too stressful not knowing how many days you will be granted…

Yes but now the second extension is only 7 days! So that means, you get 60 days + 30 days extension, then go out, get stamped again 60 days and after you get only 7 days…So if you want to stay 6 months, you have to get out 2 times or stay for 3 weeks in another country 🤷‍♀️
