Can I renew my Indian passport from any Indian city apart from a?
I understand you have change your address. This means you have to apply for renewal of passport with a new address proof. No comes the part, where will you apply. As far as known to me you can apply in any PSK in India, but why will you visit a PSK that is not the nearest PSK. Sometimes it makes sense, e.g. Dharwad is easily connected to Mumbai or Pune than Bangalore. So people might prefer not to go to Mysore or Bangalore.
