When I entered Thailand in March (visa exempt) I was given a 60 day tourist stamp instead of a 30 day stamp. The immigration hotline told me that I needed to go to MTT to correct this. I asked what to select in the drop down menu and was told go with "extension" and then let the officer know that I actually need a correction when I arrive. That doesn't really sound right to me. Can anyone confirm that stamp corrections were moved from CW to MTT? Thanks in advance.

Counter K it is. Thank you so much!
