I done mine in Sept and no insurance requirements, ensure you are applying on the correct website and not some Scammers! There are plenty of bogus sites out there!
I started my LTR When my nonO was issued, bank now updated, docs all approved so far, now awaiting final review, hopefully it will be issued before my o renewal is due in Jan 26. Double checked with BOI on progress and they confirmed that final Govt checks are taking place. They respond very quickly to any questions.
ive got mine and it took 3 weeks, I had to submit more docs. and that is through the official Thai embassy for my Non O Visa which I have. my LTRV is in process and hopefully I will collect in Bangkok when I get there.
You MUST apply for your non O Visa whilst in the UK. You cannot do it from Thailand. It should take around
***
weeks if you get all your paperwork in place. Look online to apply and get all your ducks in a row before starting. There is a checklist to follow, read it thoroughly twice and then apply! Good luck.
