Do people have any experience with conditions or limits of how many Thailand single/double entries you can hold in your passport? (providing all legal documentation requirements are met) Also concerning in country extensions to the single/double entry. I have been told by a friend that he specifically asked this question to a senior member at Thai Immigration and was told that it was unlimited. He is an Australian passport holder, mid 40's living in Thailand but travelling outside (generally monthly or bi monthly) as am I. Interested to know about people's experiences and variations from different Countries. Thanks in Advance.

The only limit is the number of pages you have in your passport for them.

There are limits on how many you can get from the same embassy or consulate back to back. But some have no limit.
