Guys, Have any of you applied for NRN card? If so, I'm sure you obtained NRN visa when you travelled to Nepal. I know NRN cards are valid for 10 years, but what about NRN Visa. Is it valid for only 30 days, or 1 year, or 10 years?

Very polite request, please do not send me URLS from Nepali immigration website. I've read it all, and only got very confused, since the info out there is very inconsistent.
