Hi I'm looking to stay in Thailand for about six weeks in the summer of 2013.
Has anyone any info on how to get a visa and from where?
Kenhulme where are you staying in Thailand? Anywhere near a Border crossing for a visa run?
Costs around £ 35 for a 60 day single entry visa
Arriving Bangkok but will be staying in Khon Kaen
Ken, apply for the visa as N Barton has suggested - takes about a week by post. The visa will have an expiry date on it but providing you enter before that date, the visa lasts for 60 days from the date of entry regardless.
If you are planning to stay in Thailand for six weeks, you probably need to apply for a tourist visa as the visa exemption is only allowed for maximum of 30 days stay. If you want to visit Thailand without a visa, you can immediately schedule your flight holding just your passport and plane ticket through visa exemption. However, as what I've mentioned, you are only allowed to stay for 30days in Thailand and you need to exit the country. May I know where are you coming from? Because there are only 48 countries I think (not sure) who are entitled for this benefit.
All the best!
