I think if they had to, they would not have a problem meeting the financial requirements individually.. But if they can avoid transferring 2x 800.000 to Thailand I think they would prefer that.. And as I understand from Robert Lagas answers, that is possible with the dependent extension based on extension based on over 50.
Can do ;) It was just my two cents. It does happen, but dont count on it! Maybe Buengkan being such a small, and relatively new, provinse is different than most. Been coming there for years, and know a lot of the faces, and they (most of them anyway) know both me and my father.
I have.. Also for the 24 hours after entering Thailand.. It depends on the officers and your relation with them. I cant speak for others, that's just my personal experience.
I personally have a good rapport with several of the IO in Buengkan.. They will accept small errors with a smile.. To show my gratitude I occasionally bring a bag of fruits for them when I go there ;)
