My chihuahua / terrier mix passed this year (sadly), but before that I was looking into bringing him to Thailand. Ask your vet. Mine knew exactly what to do / what was needed.
to be clear — after that first night in a hotel I’m going to the home my wife and I have in Issan - and at day 59 I may want to go to immigration and buy another 30 days. If my wife / I haven’t filed a newer TM30 at the house (me having been there 58 days by that time) — is that a problem? …or will they just be ok with the TM30 the hotel filed on that first night (likely in BKK)? …that’s where I was going…
what about the +30 days extension on a 60-day tourist visa? Same? (…1 night / 1st night in a hotel is enough to count to get the renewal at immigration?) [in Udon Thani, BTW]
I got a prenuptial drawn up (expensive to do) — and she wasn’t having it. I married her anyway, but I did already have the usufruct, though, so that gave me some comfort. In the end I agree with only keeping money you need for your visa renewal and living expenses in your Thai bank account / transfer each month from outside Thailand as needed via Wise. …and just keep loving her / working to be happy together in the marriage — hope for the best. 🤷‍♂️
