Hello Are the customs rules for a US Citizen same as it is for a Nepalese citizen travelling to Nepal from US at the airport in KTM? What kind of visa is required/recommended to stay (family visit) for 4-5 months in Nepal. I found visa info on 30/60/90 days stay but not for longer than that. Also, if a US citizen still has the Nepalese passport can they use that to fly to India from Nepal and back? Thanks
