Check the requirements for the Thai embassy where you'll be applying. They each set their own requirements.

It's optional. Leave it blank without any issues.

You have not had a stay that can exceed 90 days yet, so you are not subject to 90 day reporting.

Even after you convert to non-B visa, that is only a 90 day visa and not subject to 90 day reporting.

When you go to get your first 1-year extension based off work from your non-B, they will put a piece of paper in your passport that will give you your first 90 day reporting date. Because the 1 year extension will be the first stamp you receive that allows you to stay more than 90 days.

there is no fee to enter Thailand. If you fly in any fees are covered as part of your airfare.

I don't think the Thai government will be sympathetic to someone willingly becoming stateless in an attempt to obtain Thai citizenship. That process is a last resort for people who have no other option.

I believe it's very far from that simple. Stateless people in Thailand have to go through huge hurdles to get citizenship, it's not as simple as just having a relative that already has it. Half of my spouse's family and many of their friends are still officially stateless without a Thai ID card because it's expensive and in some cases all but impossible to obtain it, despite their families living in Thailand for multiple generations.

And the fact that you already have a US passport means you're no longer stateless.

It's for anyone who can qualify for it. But if having a path to PR or citizenship, the ability to get a job in Thailand, or having a Thai bank account are important to you, then the DTV is not conducive to any of those.

Push more people to use agents

@Tom *******

it's not asking for Thai bank account. It's asking for any bank account.

If applying on the basis of Thai family, then yes. The non-O based on retirement is 800,000.
