Are you thinking of going forth there?
No, I'm definitely ordaining in Australia with Ajahn Brahm. I'm just on a sort of anagarika holiday... 8 precepts and white clothes while travelling... I look like some kind of nut.
I'd go for ordaining locally in the USA, even though the waiting list is really long there. You can go to be a monk in Thailand later. At least for me, the combination of both adjusting to monastic life AND adjusting to Thai culture would have been a bit too much.
Best of luck to you! Oh, the other thing I remember someone telling me is that if they don't reply, just get your stuff together, get the long tourist visa, and just arrive. That seems to be an okay way of doing it if they've not replied.
