Visa requirements for E-Visa India depend on your nationality and the purpose of your visit. Generally, E-Visa to India is available to citizens of numerous countries for tourism, business, and medical purposes. To apply, you need a valid passport with at least six months of validity remaining from your planned date of entry. The application process is typically done online through the official Indian government website or other legitimate platforms, where you'll fill out an application form, and upload a recent passport-sized photograph, and a scanned copy of your passport's bio page. A non-refundable fee is usually required, and processing times vary, so it's essential to apply well in advance of your intended travel date.
