If u have come as a temporary work and have not brought any property..no need to learn the language..but if u plan to settle there...u must learn it...I think India should make this as a law...otherwise regional languages will loose existance.My friend,please understand...India was not a single hindi speaking country when British came.It became a country on the basis of diversity and protecting regional culture.It will cease to exist as a nation if it's multicultural and multilingual roots are not protected...as every other state will demand for separate nation.Jai Hind,Jai Maharashtra!
