Visa & Entry

US passport holders need a visa to enter India. The eVisa is the standard option for tourists, applied for at indianvisaonline.gov.in. The 30-day eTourist visa costs $25 (single or double entry). The 1-year and 5-year eTourist visas cost $40 and $80 respectively, both with multiple entries and a maximum stay of 90 days per visit. Processing takes 3 to 5 working days. Upload a passport scan and a recent photo. Passport must be valid for at least 6 months beyond the date of entry with at least 2 blank pages.

The eVisa is accepted at 28 designated airports including Delhi (DEL), Mumbai (BOM), Bengaluru (BLR), Chennai (MAA), Kolkata (CCU), and Hyderabad (HYD), plus 5 seaports. At the airport, proceed to the eVisa immigration counter with your printed eVisa confirmation. Biometrics (fingerprints and photo) are captured. India also offers traditional paper visas through the embassy with longer validity options for business and employment.
