Do Hong Kong passport holders need a visa to visit NP?

HKSAR ordinary passport holders can get a Nepal tourist visa on arrival at Tribhuvan International Airport (Kathmandu) and at major land borders. Uniquely, the visa fee is waived (gratis) for Hong Kong SAR and Chinese passport holders, so the standard 15/30/90-day VoA is free of charge. Bring a passport valid 6+ months with 3 blank pages and a passport photo. Nepal classifies Hong Kong SAR ordinary passport holders as eligible for visa on arrival (VoA), and the Hong Kong Immigration Department's official list confirms VoA for stays up to 3 months. The distinctive feature is that Nepal grants "gratis" (no-fee) visas to Chinese and HKSAR passport holders, so while travelers from most countries pay USD 30/50/125 for 15/30/90 days, HK holders receive the visa free of charge. The visa is issued at the immigration desk at Tribhuvan International Airport in Kathmandu and at designated land border crossings. An online pre-registration form (sometimes marketed as an "eVisa") is available to speed up the airport queue but is optional and not a separate mandatory e-visa. Travelers should carry a passport valid for at least six months with three blank pages, a recent passport-size photo, and proof of onward arrangements. The total cumulative stay for a tourist in a Nepali visa year cannot exceed 150 days, and the VoA can be extended at the Department of Immigration. Because the no-fee channel for HK holders is well documented by both the Nepal Consulate in Hong Kong and the HK Immigration Department, the verdict is visa-on-arrival (fee-waived).
