I guess all depends on your eligibility on the visa itself but they all come with pros and cons. I’ve done numerous marriage visas for clients who ended up changing to business visa instead because either 1) the marriage didn’t go as planned 2) they want to have a business and earn money while staying in Thailand. So B-visa is the way to go. A bit more complicated in the beginning but safer in a long run and also if handled by the expert and a bit of a shortcut then it’s fine. No need to worry about working illegally or choosing the wrong wife 😅. If you are interested or need more info you can check it out —>
