Paradox, if you have family members in ktm and depending on how long you plan to be in Nepal, you may be able to get relation/family visa . So you would get the minimum 2 weeks visa for $30 at the airport, then visit the immigration office with a family member who can vouch for you. I believe it is $10 per month for single entry and additional $60 for multiple entry
