He don't you know that Hong Kong has asked all Nepalese not to bother applying for their Tourist Visa... they don't even accept aplications for Visa from Nepaelse anymore......
Transit Visa means you can hang around in that particular city for couple of days, meaning go out of the airport.... It's not gonna happen when they are already not giving Tourist Visa to Nepalese...
But if youare going via Hong Kong, you can still do that.. but you cannot go out of the airport.... just get off at hong kong airport.. hang around to change the flight, if it will take say 5-12 hours to catch next plane.. you might have to sleep inside the airport.
Visa Aplly nei nagarnu bhanchhan, mula ke garna sakinchha???? Paryo hami Nepali..... behal chha ,, ke garne!!!
