So what am i saying? The official language of Pakistan is English, the National language of Pakistan is Urdu, whereas Provinces have their regionnal languages. Difference is India have Hindi as official & English too as official & no national language.
What am saying is that there is no national language in India. And only the Central Government has Hindi and English as the official language.
The state governments have their own official languages. Meaning that they can do their official paper works and proceedings in their own languages like Marathi, Malyalam, Tamil, Kannada, Bangla, Telugu, Punjabi, Hindi, Urdu, Nepali and so on.
Not the same in Pakistan as far as I know? Can the Punjab provincial government in Pakistan do their paperwork in Punjabi?
