I have been traveling frequently in Thailand for the last 30 years. But this year a had a new experience: I arrived in Subvarnabumi, and prior to that I had a TR visa made at the Thai Embassy in Copenhagen in my passport. So that should give me 60 days, which was fine as my stay is only 57 days this time.
Now yesterday I noticed, that the immigration-officer at the airport simply haven't noticed the visa from the embassy, and have given a 30 days stamp - in other words a visa at arrival.
Does that give any problem when I have to leave Thailand? I still have the valid 60 days TR visa in the passport. Has anyone had a similar experience, and if it is a problem - how did you solve it?
