From what I’ve been reading, as long as you can show proof of residence outside of Thailand, you can apply anywhere.
I’ve been doing a lot of research on this as well. I’m residing in Thailand at the moment with my Thai wife. All my identification shows a Canadian address so I think I’m ok. All I would have to do, if the visa is approved, is leave Thailand and then re-enter.
Like Tod has mentioned, go and try to apply for the extension. Worse case scenario is you have to pay a fine for not having the TM30. The fine is 800฿ and up. I paid 800฿ last month but have heard of others paying more.
You’ll end up paying that for a hotel for the night.
1900฿ for the extension, the additional 800฿ for the TM30 fine and 500฿ per day for overstay.
Please note, if you’re going to the immigration office today, be prepared to be there all day, as Fridays and Mondays are the busiest times to go.
Large a/c bus from Ekkamai 131฿ or you can book a taxi which is approximately 1200-1500฿ and takes about the same amount of time, 2-2.5 hours depending on traffic.
I suggest you use Agoda for looking at or booking a hotel. You can use the filter option to pick and choose what options you want/require. I’d say you won’t have to worry about the hot water as almost every rental there will have it.
If you haven’t been there before, I would say 5-7 days to get the feel of the whole of Pattaya. If you’re going to party and drink only, a couple of days would do. If you get bored, jump on a boat over to Koh Larn for the day or stay a hour there.
