I'm curious about the following situation:
I'm in my home country now, and I'm applying for a Tourist eVisa, but I'm not sure if I'll get my eVisa in time before entering Thailand.
So then I'll enter Thailand with a Visa Exempt.
My question is: could I, after entering Thailand, go to the border of (let's say) Mae Sai/Tachilek which is open again if I'm correct, and then re-enter Thailand with that Tourist eVisa that I've gotten too late?
