Worthless suggestion. Stop thinking or dreaming about these nonsence issues - scrapping nationality or nationality certificates based on ones abilities to speak Nepali or on some other grounds. you should know the facts that many Nepalese who live even in the heart (capital) of Nepal (eg, Newar elderly people) can not even speak Nepalese properly, forget about Nepalese residing in the Southern plain or Dolakha/Solukhumbhu/Dolpa of Nepal.
