Applying for entry into India starts with a short but essential checklist, and getting it right the first time saves a lot of back-and-forth later. Every applicant, regardless of visa type, submits two baseline items: a clear passport bio-page scan and a recent digital photograph. From there, the Documents Required for Indian e-Visa page breaks things down by purpose of travel.
Business applicants typically attach a business card along with an invitation letter from the hosting Indian company, though sports-related trips instead need government sports ministry approval. Medical and Ayush categories rely on hospital-issued invitation letters confirming treatment plans, while conference delegates need clearance from both external affairs and home affairs ministries alongside an organizer's invitation.
Transit travelers face a different set entirely confirmed inward and outward tickets, plus proof of eligibility for the destination country beyond India. Production and investment visa holders submit sponsorship and dispatch letters tied to their employer and host company.
Since paperwork shifts depending on the exact reason for visiting, cross-checking the intended purpose against this list before submission tends to prevent avoidable processing delays later in the review.
