With a marriage visa, you only get 1 year at a time (90 days per entry if using a multiple entry marriage visa obtained abroad) but you are work authorized once you apply for a work permit.
With a DTV, you can't work for a Thai company.
However, unless you're expecting to receive a job offer for working in Thailand soon, you might as well apply for a DTV and then, should you get a job in Thailand, you can always convert it to a non-B plus work permit or go out of the country for one, in order to ensure you are able to work legally in Thailand.
Thus, a DTV is better, provided you don't have a need to work in Thailand for a Thai company.
A marriage visa is better, if you do have that need.
100%. It still requires border runs, even if they're not as frequent as with existing/previous multiple entry visas. That alone makes it less attractive to many people.
I also agree that they might tighten up or even scrap the soft power category.
That's a good point. I'm sure the MFA know what they're doing and his constant criticism of them, as if they were a completely incompetent agency for creating this visa is another thing that completely confuses and annoys me. I mean, they're a branch of the Thai government that deals with external affairs, including issuing Thai passports to Thai citizens and visas...they seem pretty competent to me.
Exactly and thus it's more than absurd to think they would create a visa class that suddenly can't be used over the course of 5 years as intended for no reason.
Generally, you don't come in for interviews once the e-visa system goes into effect. You are simply asked for more documentation via email or possibly phone call.
