Is it possible to renew your passport when you are a student in?
Yes. The Indian High Commission is always available to help you. I was on a deputation on job in UAE and my passport was expiring in a few months. I apptoached the high commission and they just stamped a 1 year extension of validity. Nowadays, Indian High Commissions have outsourced the front end of these services to travel companies. They have online portals where they ask you to submit copies of all sorts of documents required. You can call them and get guidance too. Once they are sure all documents are in order, they ask you to post your original passport, along with other documents to the Indian High Commission. Since all your documents are pre-vetted , they cancel your passport and prepare a new passport for you with 10 year validity and post both passports back to you in 3 to 4 days.
