, most Immigrations will give you a Residence Certificate even on visa exemption. The well-known exception is Bangkok. You will need your landlord (hotel) to do a TM30 reporting, which you show to the IM.
1) If you want to buy it in your own name, you'll need a Residence Certificate from Immigration. 2) For the first 3 months of your stay you can use an international driver's license. For more than 3 months you'll need a Thai driver's license. Both need to be for driving a motorbike. 3) There are second-hand motorbike shops everywhere. I would buy a new one to be sure it has been maintained. 4) If the bike is standing still when you are not here, then prepare yourself for the battery to be replaced and the tires to be lifted every time you arrive. 5) Annually, the bike needs a repaid license.
The only rule is that the Thai account cannot be a shared account with your wife. If a shared account then only 50% of the amount on the account will count for you. In other words, you will need to double the amount on account.
The Royal Thai Embassy in Sweden has just informed me that Non-O on the ground of marriage has no financial requirement even though the eVisa system mention such a requirement.
, but I have tried it. Have you? It has nothing to do with the requirements but with when the IM will extend a multiple Non-O. Until the multiple Non-O has not expired there is really no need for an extension as you can just bounce the border and get new 90 days on return.
You can get two times a 30-Day visa exemption by land borders in one year. Unlimited by air - until the IO decides not to... Each 30-Day exemption can be extended by 30 days at IM.
