Changing place of birth on passport

Hi All,

I need to get my place of birth corrected on my passport and I understand that I need to get first class magistrate's order for that. I want to understand if the magistrate has to be from the same place as my actual place of birth or place of birth as recorded in my passport? Can you please also let me know the time it takes for this process ?

Kindly refer me some lawyer in Chandigarh who can help me out with this.

Thanks.

Puneet
