Government of India has launched electronic travel authorisation or eTA for India which allows citizens of 180 countries to travel to India without requiring a physical stamping on the passport. This new type of authorisation is called an eVisa India (or electronic India Visa).
It is this electronic India Visa online that allows foreign visitors to visit India for five major purposes, tourism / recreation / short term courses, business, medical visit or conferences. There are further number of sub-categories under each visa type.
All foreign travellers are required to hold an India eVisa (India Visa Online application process) or a regular/paper Visa prior to entry into the country as per Indian Government Immigration Authorities.
Note that travellers to India from these 180 countries, which are eligible to apply for an India Visa online are not required to visit Indian Embassy or Indian High Commission for the purpose of getting a Visa to India. If you belong to an eligible nationality, then you can apply for an India Visa Online. Once the visa to India is being issued in an electronic format, then you can either carry an electronic copy on your mobile device or printed copy of this eVisa India (electronic India Visa). Immigration Officer at the border will check that the eVisa India is valid in the system for the concerned passport and person.
