that is not correct. Though it's seems unlikely that OP would fall into those categories, having a non-o or extension thereof based on either marriage to a Thai or being the parent of a half Thai child both allows working too.. Just as an example. There are also various types of smart visa that allows work. Saying the only visa that allows work is a non-b is just not correct.
Best way is for someone to bring it. If that's not possible, avoid DHL and the other couriers. If you use them you will get hit by customs for sure. Just send it with regular tracked and registered mail. I have received several ipads and several laptops this way from Denmark. One at a time. Never an issue. No customs and took about a week each time.
my extension expires 31 October, and it accepted that I chose 31 December 2024 as checkout date. It's in the system now when I search, and has a green color showing its okay and processed. Strange indeed if it doesn't work the same for all users.
I actually did, but they do not mention what to do when you don't have a checkout date. And the QA is lacking too, to say the least. Hence why I asked on here.
as with everything else here it depends. On what office. On what specific officer. On what day of the week. On what color socks your had on last Tuesday. Your experience in Sisaket may (and will) be different from the experience of others. Both in Sisaket, but more importantly in other immigration offices. Best advice is to check with your local office as advice from a different office might be useless.
have you ever visited a Thai government office besides immigration? That's just how it is. For the Thais too. People in different offices are sometimes queueing outside for hours and hours. Bring some shade, and make use of the always present food/drink vendor when more than 5 people are gathered. 🙏
