Casting some aspersions there Charlie. You on the old "Farang comes to Thailand to screw Young's girls" predictable BS. I am married, live far away from "girly bars" in rural Thailand and am bringing up two adopted children with my wife. If the lady thinks she is going to land in Thailand without the least bit of knowledge about the country other than watching re-runs of "The Beach", with two kids in tow, on a teaching English course and no other source of income, no Thai language (you just taught her her first word, ฝรั่ง and it's meaning) , not to mention visas, she is in cloud cuckoo land. And you shouldn't be stereotyping people either or maybe I should be thinking about how YOU got along being a single white female looking to make money in Pattaya. Plenty of them too eh?
I speak Thai stutteringly. I'm sure anyone attempting to speak Thai are aware of the difficulties. As I said, the questions of tone and vowel length are evident if one can read.
Sorry to hear that if everything is in order in my experience only they will endeavor to get it on time but...Anyway the lad can arrive on visa exempt.
