Absolutely no problem. All visas are fine to use with just a one way ticket. The only visa for which I'd recommend having an onward ticket (though it might not get asked for) is if you possess a valid single entry tourist visa.

How far back do they want you to go? Just show all the previous visas issued over the past year or two but don't bother with any visas issued in previous passports.

Anonymous participant Most people are saying it's a type of tourist visa but in effect, it's kinda more like a non-immigrant visa.

The issue is, you can't qualify if you hold a visa issued outside the country, especially one where you're not authorized to work.

Nope, because to qualify for permanent residency, only a non-O or non-B that are extensions of stay (not the visas you get outside of the country) plus employment in Thailand are acceptable (meaning you also need to hold a Thai work permit).

You don't qualify for permanent residency if you're on a laborer visa (for Vietnamese, Cambodian, Burmese and Cambodian nationals), a retirement visa, tourist visa, any visa issued abroad (including the DTV), or even the LTR or elite/privilege visas.

A smart visa might qualify (not sure) but otherwise, only non-O and non-B extensions of stay...3 consecutive ones plus a minimum income of 80,000 Baht per month (40,000 if married to a Thai) for a minimum of 36 consecutive months. If any months are missing, you start from scratch.

Not really. You can simply show the funds came in from abroad.

The tax thing is still unclear and not yet enforced (it might never be, or it might only be enforced in a few years...anyone's guess right now). The point is, immigration is most definitely not interested in it. It would be hilarious if they asked for tax proof while you're standing at a land border coming back in. If that ever happens, foreigners will stop coming to Thailand so I don't think that's something to worry about.

@Charles *********

Totally agree. At this point, I wouldn't worry about it and not take any action. Unless enforced, at which point you can decide how to deal with it. At this stage, nothing will happen.

@Kelly ******

It gets complicated if you're coming and going regularly, even if you happen to spend more than 180 days cumulative total in the country. Thais are bad at math, I can imagine the confusion if you're trying to show records of having spent 220 days in the country in one year, but this is made up on 25 separate entries!

Exactly the same for me. I have my own sole proprietary company, but I didn't provide it for the purposes of my application. Instead, all employment documents were from my employer.

@Thiên *****

Not necessary. Many applicants are entering Thailand by land after applying for a DTV in a neighboring country.
