Those travelling for tourism and other short-term visits, (like business and medical visits), can apply for an e-Visa, while those planning to study or settle in India will need to apply for a traditional visa. The e-Visa for tourists is valid for visits of up to 90 days (180 days for citizens of UK, US, Canada and Japan), while the business and medical e-Visas are valid for stays of up to 180 and 60 days, respectively. It’s not necessary to hold a transit visa for those connecting through Dubai and Doha.
