You should probably ask the immigration office where you plan to apply. The rules say the money is supposed to have come from abroad, but I understand that officers can waive that if the funds have already been in Thailand a long time. This may not work, since they may see it as your wife's money, not yours, but it's worth asking before you go to the trouble of transferring more - the worst that can happen is that they'll say no.

To show that the funds came from abroad, your bank should be able to give you a paper that's usually called a "credit advice" - it's separate from the bank book and bank letter, which you also need. (The proof that the money was transferred from overseas is only needed for the initial Non -O application, not for any subsequent extensions.)

That isn't true. The Thai marriage certificate is legal on its own, and no "certification" by the embassy is necessary (or even possible).

The official policy since 30 June 2020 is that you do not need a new TM-30 as long as (1) you are returning to your previous address where you already filed a TM-30, and (2) you traveled using either a multiple entry visa or a re-entry permit. Whether your particular immigration office follows that official policy is a different question...

@Veep ******

This announcement says that as of 30 June 2020, landlords do not have to do a new TM-30 for someone who goes to stay temporarily in a different place and then returns to the same residence where a TM-30 was already done, as long as the person was using either a multiple entry visa or a reentry permit. (In other words, coming back on a new visa or new exempt entry would require a new TM-30.)

is correct that Chaeng Watthana will accept bank letters up to a week old, as long as the bank book is updated on the day of application. That's in their written instructions, and is also my personal experience - I got my bank letter a day or two ahead of time for my last several extensions. I don't know about Jomtien, though, which is where the OP plans to apply.

As others have noted, shipping the truck is probably not even permitted anymore, and would be expensive and a hassle (duties, maintenance, wrong side of the road, etc) if allowed.

For the rest of the stuff, though, ship it with an experienced company and you'll probably be fine. I don't know that FedEx is really the way to go, since my impression is that their packages get more scrutiny than regular ocean shipments, but I don't know that for sure.

I shipped an entire container of used personal effects here, and what I ended up paying in duty was a lot less than what it would have cost me to replace my espresso machine alone here. When folks online say, "just buy it all here, appliances are cheap in Thailand", what they don't add is that CHEAP appliances are cheap here - quality appliances are absurdly expensive.

My actual shipping and clearing costs were paid by my former employer as part of my retirement, so the calculus was different than yours, but what you're envisioning isn't ridiculous. FYI, the duty on my shipment was about $600-700 if I recall; the crates weren't opened, and I was issued an official receipt. And you don't need to have a visa already to ship the goods, but you will have to provide your passport to the shipping firm when the stuff arrives so they can carry out the clearance procedures.

Good luck to you.

Usually the contract will say something like you have to give reasonable access to the landlord to show the place to potential buyers, but he would also stipulate to those buyers that the unit comes with a tenant for the next x months, and they would honor that (but might or might not renew your lease).

The US Embassy will normally accept any accurate translation - the translator doesn't need to have any special certification.

For Don Muang, the long-distance train will probably even stop at Don Muang station on the way to Bang Sue, making things even easier.
