Let's say I apply for a DTV visa online and get approved, but then find out that there is a small error in my application and the e-visa itself. However the consulate have already approved and issued the visa so they can't cancel it. In this case, if I apply for another DTV visa with all the correct information and they approve it too, what happens? Can I have two online visas being valid simultaneously? Will i have any problems entering Thailand in this case? Can I enter and cancel the "wrong" visa when I'm already in Thailand?
