When you apply online for an Indian e-Visa (e-Tourist, e-Business, e-Medical, or e-Conference), the Bureau of Immigration issues an official 'Electronic Travel Authorization (ETA)' PDF with a barcode and QR code. You must print this ETA document and present it upon arrival at any of India's 31 designated international airports or 6 seaports, where immigration officers capture your biometrics and stamp the e-Visa into your passport.

No. Under strict regulations of the Indian Ministry of Home Affairs, any traveler who currently holds or previously held Pakistani nationality—or whose parents or grandparents were born in or permanently resident in Pakistan—is strictly ineligible for the online India e-Visa / ETA, even when traveling on a UK, US, Canadian, or Australian passport. Such travelers must apply for a regular paper visa through the Indian High Commission or VFS Global.

The 30-day e-Tourist ETA is valid for entry within 30 days of grant and permits a double-entry stay of up to 30 days from arrival. The 1-year and 5-year e-Tourist ETAs are valid for 365 days or 5 years from the exact date the ETA is granted, allowing multiple entries with stays up to 90 days per visit (or up to 180 days per calendar year for UK, US, Canadian, and Japanese citizens).
