visa
US passport holders need a visa to enter India. The easiest option is the e-Tourist Visa, which you can apply for online at indianvisaonline.gov.in.
Apply at least 4 weeks before you fly (we recommend applying as soon as you have flight tickets). Make sure your passport is valid for at least 6 months past your travel dates and has 2+ blank pages.
Make sure to print the actual e-Visa (ETA) document itself, not the confirmation email. You'll need to bring the printout along with your passport to present at check-in.
