An India tourist visa has a validity of 6 months to 10 years. This is a multiple entry visa. Each entry has a limited duration of 6 months. India tourist visas are usually issued the same day for walk-ins who arrive before 12:30. Applications that are mailed in take 10 business days. The fee for the India tourist visa depends on the length of validity. The fees are $60 for up to 6 months, $85 for 6 months to 1 year and $150 for more than 1 year to 10 years.
