If it is a new visa, they have simply lost millions of baht in extension and visa renewal fees. Considering the fact they was whinging about how much visa exempt cost them in lost revenue (7.1 billion baht was the quote) I'm finding it hard to believe they would come out with this visa 😊
There screen certainly does show that information Tod. If I fly into any airport other than in Bangkok, and even at times into Don Mueang where they are not familiar with a TE visa, they call up a screen that lists visas and how long each visa needs to be stamped in for.
I personally think it would be picked up on if you tried to use it as multiple. I think it would show when they look at there screens to check the type of visa and how long they should be stamping you in for.
