Visa options for India
Electronic visitor visa
Travelers need a visa to visit India for Business or Tourism. An India e-Emergency eVisa is the fastest and easiest way of obtaining a visa for India because travelers can submit their application and supporting documents online. Once the application is approved, travelers receive their eVisa confirmation electronically. A valid visa is required to board the flight. If the visa is expired or doesn’t match the traveler’s passport information, travelers will not be able to board their flight. Entry to India with an eVisa is supported at 28 airports and five seaports.
