Some more stats for my journey so far if of any use:
20 Sep - Applied for, LTR Working from Thailand Professional
19 Oct - Request more documents
4 Nov - Approved
(then some time to organise health insurance went back to BOI on 14 Nov. I used the submit later option for insurance previously.)
24 Nov - Health Insurance rejected and I've gone back to BOI to explain why it is valid
I was also wondering for the TM6 landing card, 'Purpose of Visit' what did those already landed with this visa type put?
Employment doesn't seem to fit as I wouldn't be employed by a Thai company. Business seems more related to business trips or running a business from Thailand. Seems like 'other' would be the option, as my intention is to work for my overseas company and live in Thailand.
But would 'other' maybe confuse and invite immigration questions?
