I did get back to the embassy; they corrected it with a pen and put an official stamp over it. I don't qualify for a visa exemption, so guess this is the only way to go forward. I fly in on the 27th morning (in two days) and hope it all works out.
I applied and got approved for my Thai tourist visa. It is a sticker visa; unfortunately, I found the passport number wrong on it. Do you think I should be concerned about it, or will it be okay?
