How many times can you re-enter Thailand on a tourist visa and extend your stay by doing a visa run?

Now I try and avoid them , and line up with a male officer

Nearly all bad stories in immigration are with a female Immigration Officer.

, yes it happened to me about 16 months ago with a lady IO. - I travel to Thailand 4 times a year for weeks at a time , on 30 day visa exempt. She questioned me why I come so often , do I have a wife or gf, what I do, where I staying etc ? And next time I need a proper visa. As I was coming back in 10 weeks I did a lot of research , called the Thai embassy in Sydney, went to a few visa shops in Pattaya, all gave different answers, , I just went with what the Thai Syd embassy told me, "there is no set rule on the amount of times flying in and out on the 30 day exempt visa, it's up to the discretion of the Immigration Officer on arrival.

..okk..i understand..thats true...first time when i got the problem about it...was becouse of a lady.....

Yes no limit (air), but always remember it is ALWAYS up to the Immigration official. So if they decide that you have 'Too many' in their eyes, they may give you a warning. Always carry 20k baht in cash to support your stay, should they ask (as this is a requirement whether they ask or not). I would also recommend choosing male IO's at the airport and not female as they like to make a scene a lot more than the men. (again not sexist, factual).

thank you Tod Daniels ,excatly this i want to know it.... no rules against....thx a lot

, you can fly out and back in the same day without a problem I know people who fly to KL in the morning turn right around and take the next flight back to bangkok.

Now you might be questioned by the people at passport control when you stamp back in (especially if you have a history of living here on back-2-back visa exempt or tourist visa entries, BUT there is no rule against doing it.

i asking michael ..about it . becouse i want to know it

@Gi**

, you mean there is no limit on 30 day visa exempt entries by air. ;) As people have mentioned there is a limit of TWO 30 day visa exempt entries by land in a calendar year.
