You may not want to call spade a spade but the fact is Nepal of all the countries in the world is home to largest population of Indian citizens (NOT Indian origin Nepali citizens). Per wiki Nepal has over 4 million Indian citizens living in Nepal. That's 40 Lakh! Majority live and work in KTM valley.

Thanks India for your assistance during relief efforts and also not forgetting about your own citizens living in Nepal.
