if you're scared for any reason, I suggest going to Mexico and getting stampped, because it is easier to get visa stampped in Mexico or Canada. Also, if they ask for any supporting documents, you can always contact you company or company attorney for prompt assistance. I have seen people with the strongest cases go to Mexico for Visa stampping, why take unnecessary tension while flying to Nepal thinking/fearing if you will or will not get the visa.

wherever you go, Good Luck to you.
