Yes from their Facebook page. Check it out. Nothing mentioned on their website yet but it's Thailand. Normally, most announcements of this type are more likely to be shared on Facebook first, with websites updated later.
Ditto. I had an appointment for Laos for next week, but have canceled it and am going to Taipei instead. Otherwise, I'd need to wait until at least late November to go to Vientiane and there are also concerns about whether they require translated documents to be notarized, which further complicates matters.
Well, the company has to be real and they can presumably check that on various online databases based in the country the company is registered in. If it checks out, then the letter presented is likely to be legit too.
I was told by Vientiane the money needs to be banked for 3 months. Savannakhet is possibly 6 months; not quite sure. In any case, they're quite strict and best to use Taipei instead.
