Can I apply for an India visa on arrival, at the airport?

No, it is not possible to apply for an India visa at the airport. Eligible citizens traveling for leisure/tourism purposes have the option to apply for an India e-Visa online, before they depart for India, which will allow them to get biometric information taken at the airport and the visa stamped inside the passport on arrival in India. However, it is very important to know that the India e-Visa must still be issued in advance of departure; the process takes several days and cannot be done on arrival in India.
