Here is the ideal scenario I can think of -

Every Universities/Colleges that has (x or greater) number of Nepalese Students should elect a student govt body to head the Nepalese Student Organization. Someone who is outspoken and can speak for the concerns of future/current/prospective students for that particular university, and please let it be autonomous. You dont need a nation-wide scoped Nepalese student organization to listen to every Nepalese guy/girl that lands at the US airport. But you need participation from the elects from all autonomous organization to a bigger organization (hierarchial) to voice your concerns. That can be simply an open forum with all elects together (Mailing-list/Website) and the content open to public.

When you have many split-autonomous government bodies working for their students, with ideas of helping and making everyone feel home, you could share your success stories to some other government bodies who are struggling through the open forum. That is the whole idea of diversified working groups.

Same applies to Young Professionals , and even Families/Kids.
