DTV Visa Question, help 🙏

Hello everyone! Sorry for the long post but I feel like this is the best place to ask about DTV.

For context, I’m 19 years old with an Italian passport, and I’m planning to apply for the DTV (Destination Thailand Visa) at the Italian embassy once I turn 20. I know I can’t apply just yet, but I’m trying to gather all the info in advance so I can be fully prepared.

I’ve read that the requirements and strictness can vary a bit depending on the embassy, so I’m hoping someone here who has already obtained the DTV can offer some insights or advice. Right now, I’m considering three possible ways to apply:

1. Muay Thai option

I’ve been practicing Muay Thai at a high level since I was a kid, and I always train when I visit Thailand. I’d consider applying for the DTV through a gym, but here’s my concern: would training for just 3 month at a registered gym be enough to qualify?

I don’t want to be tied to a single place for too long, I’d prefer to train at different gyms throughout my stay. If I apply under this category, will immigration later check if I’m still actively training?

2. Freelancer (Fiverr)

I’ve been freelancing as a video editor on Fiverr since I was 15, with a solid portfolio and plenty of positive reviews. That said, it was always more of a side income rather than a full-time salary. I know the DTV requires 500,000 THB in a bank account, which is not a problem, but I’ve seen mixed info online about whether monthly income is also required. Does anyone know if it’s strictly necessary to show regular income?

3. Remote work / online business

Recently, I’ve started working on my own online business (clothing brand). The website is nearly ready (I’m still finalizing the code), and I have a verified Instagram page set up for it as well. I haven’t made any sales yet, but I’m confident it will start once the site launches. Again, the issue is that I currently don’t have a record of monthly income. Is that a deal-breaker?

So my big question is:

Which of these options seems the most realistic or safest for applying to the DTV, especially at the Italian embassy?

Any personal experiences or tips would be massively appreciated!

Thanks in advance everyone 🙏
