Hello! My passport does not have my surname on and I want to update my surname on my passport as it is causing me problems in places where they need a mandatory surname. I have a student visa that expires in July 2023 and I am eligible for a PGWP but I want to make sure my details are updated and complete on my passport before I apply for the PGWP. If I change my name on my passport in India, how do I travel back? Can I travel back with my old passport plus my new passport and additional documents? I'm not sure what to do as I'm getting conflicting answers. If anyone has gone through this or knows what to do, I would appreciate your advice. Thank you in advance!
