The Indian eVisa allows eligible foreign travellers to apply for permission to visit India online before their journey. The official system covers several categories, including e-Tourist, e-Business, e-Medical, e-Student, e-Transit, e-Conference and other eVisa services. Applicants complete the form online, upload the required documents and pay the applicable fee. The passport should generally have at least six months’ validity at the time of application. Once approved, the Electronic Travel Authorisation (ETA) is sent by email, and travellers should carry a copy when travelling. The eVisa is non-extendable and non-convertible.
