Ash Raj, For Nepali Citizen You will need a transit visa while travelling  through Benelux countries ( Neatherland, belgium, luxembourg), This is new rule implemented 6 months ago. If you dont have visa , they wont even let you Board  the plane in States.

Ash Raj, Please note the highlighted part. You can  even click the link  and find the original source. Information for Visa Applicants Foreigners who intend to travel to the Schengen countries (Austria – Belgium – France – Germany – Greece – Italy – Iceland – Denmark – Finland - Norway – Sweden – Luxemburg – The Netherlands – Portugal – Spain – Estonia – Latvia – Lithuania - Poland - Hungary – Czechia - Slovakia - Slovenia and Malta) for private or business purposes may receive a visa for these countries valid for one day or up to 90 days. The visa may allow a single entry, two or multiple entries. This Embassy receives your visa application if your main destination is Germany, Austria, Belgium, Luxembourg or the Netherlands. Holders of valid Schengen visas issued by any one of the above mentioned countries do not require an additional transit visa (category A or B) to transit any other Schengen country. A transit visa is required if a foreigner wishes to travel through a Schengen country in transit on the way to a non-Schengen country. If remaining at the airport, Nepalese citizens do not need to obtain a transit visa, unless remaining in the transit area in Benelux. It is not possible to change the purpose of the visa request after submitting the application. There is no legal claim to obtain a visa.     http://www.kathmandu.diplo.de/...

Suggestions: Going to Nepal via India don’t take expensive electronic stuffs, no too much cash. Coming back, have to have proper documents i.e. US passport, Green card, otherwise, those Dhotis ask lot of questions, and might prevent you from boarding. Be careful.
