Thanks for sharing. Haven't heard of this before! Good to know. Does the wife's business need to employ one other foreigner in addition or does the lack of a ltd company mean this isn't required?
I 'm also wondering this. No 2 month requirement is my experience (Thai Child Non-O). Though not sure I see Bangkok Bank making the distinction. Still need the same cert/letter....Will find the relevant immigration rubric, and ask for confirmation ahead of time, I guess.
