To check if you require an India Visa, travellers should first identify their nationality, passport type and purpose of travel. Some foreign nationals may qualify for India's eVisa system, while others may need to apply for a regular visa through an Indian mission. The official eVisa website provides a list of eligible countries and explains the permitted purposes, including tourism, business, medical treatment, conferences and transit. Travellers should also check whether their passport meets the validity requirements and whether their intended activities are allowed under an eVisa. Checking the official information before booking travel can help avoid applying for the wrong visa category.
