I suspect they do, but might take a few weeks rather than the walk in walk out service you get in Thailand

Have you checked if you can replace Thai ID and passport in US at Thai Embassy/Consulate?

I suspect that it's mostly to do with international requirements that passenger manifest matches passport/ID details for security etc. So some airlines may be more rigid than others as to how they interpret and/or apply the regulations. Easiest to have matching documentation long term as you can appreciate.

I did my own passport translation and certified myself, which was accepted by my Amphur. I had to have an interview though to make sure I was a 'fit and proper person' to get a YB

@Ken ******

pretty sure that's not the same thing. Electoral register is only for residents and only for those over 18. It also doesn't prove nationality or provide birth details. Many countries have a central registry, particularly where they issue national id cards

Go CM office after lunch

Quite a few people pay for the Elite Visa, even though they can obtain a Non-Imm Visa by way of retirement or marriage. Horses for courses

Be aware that it is not designed to be accessed on any web browser. From memory, Microsoft Internet Explorer is the only platform on which it works consistently

It may or may not be the same for Non-B (I don't know the requirements), but for what it is worth, as soon as I hit 50, I went to immigration to convert my Non-Imm ED visa extension to an extension based on retirement. This was at CM (Promenada). Initially, they refused to do it ('you have to leave the country and get a new visa Sir'), but I stood my ground and after checking with a more senior person at immigration, they accepted that it was possible, and I got it done. I had to cancel my ED extension and then just apply for a new extension based on retirement rather than education.

If it's so easy to get an income letter from Non-British and Canadian Embassies/Consulates, it makes you wonder why so many people are paying through the nose to get the extension based on 800K in the bank from an agent if you know what I'm saying....
