If you're asking specifically for the re-entry permit application, it really doesn't matter what you put. Just make a guess, put a date, and then get your permit that you can use for the entirety of your extension. You don't need to book anything.

That's up to you. It can make getting through the border faster if you apply online a few days before. Otherwise you wait in line with everyone else for visa on arrival.

TDAC is not relevant. Departure information is not even required for the TDAC. You can just leave it blank.

@Terry **********

not necessary. Just want to make sure you don't submit the application then sit around waiting for nothing. Once you pay it should be less than a week until you have your visa.

Just make sure you realize that you have to submit your visa application online after entering Laos, but your application is not complete until you go to the embassy between 9-11AM and make the payment for the application in cash. Only Laos and Myanmar have this oddity about paying in person (and Myanmar even requires an appointment to pay.)

@David ****

maybe you "rescue" a dog some Thai person considers theirs.

Maybe a local food vendor considers your handing out free food as stealing their business.

Maybe a Thai person that collects recyclables from the beach doesn't like your cleaning up as it eats into their income.

Everything has 2 sides. Just because you consider something only beneficial doesn't mean everyone will see it that way. And Thai people are the ones you have to worry about complaining as they are the ones the officials will take seriously.

There's no proposal. These changes went into effect in February. You're way behind the news.

Is it true? Yes, it's true. Volunteering is considered work, taking a potential job from a Thai person.

Lots of people still do it.

Is it too risky? That's up to you decide. If someone complains, you could potentially be deported/banned from Thailand. Not likely, but it's possible.

The only thing you listed that is required for a non-O based on marriage is proof of funds. None of these other things are required for a non-O visa. You're listing requirements for the non-OA which is not what you are wanting.

@Pierre ********

yes. Once a marriage is registered in Thailand, you can get proof from any amphur.
