What is the difference between e-Visa and regular visa for India?

The Indian e-visa is for a shorter period of stay and it's also much easier to apply. The regular tourist visa for India requires more documents, time and is more expensive, but allows for a longer stay. Depending on your nationality, you can apply from a minimum of six months up to 10 years.
