That's the cost of the visa but not all that's required. You also need to either be a remote worker/ freelancer or apply using one of the soft power options, so you need to show your income from your work or have signed up to (and paid for) a minimum 6 months soft power activity

What visa were you applying for? Or if you were applying for an extension What extension

Anonymous participant 168 depends where you apply, some consulates will allow you to provide a sponsorship letter

You can do it for as long as you can do it then you can't. On visa exempt you can do it once for sure, everything else is a gamble. Get a visa that is fit for the purpose of your stay.

Work out your dates. This is only the 3rd of September. Regardless of that stay where you applied until the process completes

If you want to do another border bounce for another visa exempt entry I'd highly recommend you contact a border run company and ask them, they won't take you if they can't get you back in. Doing it yourself would be risky and staying out a few days won't change that

Just to clarify you each need to apply for your own visa. The primary applies first and once that visa is issued a dependant could apply quoting that visa and showing proof of relationship. Proof of relationship would be birth certificate, marriage certificate, etc. As you are not married you can't be a dependant so would need to apply directly for your own DTV using whatever criteria you meet

Anonymous participant you can't be employed in Thailand under the DTV. Put your occupation and income. If they want more information they'll ask

If you have citizenship of an European country then you should be able to apply from that country. I'd ask for a stamp from immigration when entering and hold onto your boarding card for your flight

You need to show that you have other income that you will be able to live off. Look on the 500k baht as an emergency fund, not for day to day spending. 500k baht is nowhere near enough to live off for the 5 years duration of the visa.
