I am traveling back and forth from India within the two-month period but during one single trip. Do I need a Permit to Re-enter?
This category only applies to current Tourist Visa holders who need a permit which will allow the applicant to re-enter India within 2 months after last leaving India. This permit is granted only if the need is urgent, and not for Business Activities/Employment or pursuing studies/research, etc.
If the visa holder is traveling to multiple countries on the same itinerary, no permit is needed as long as trip follows the itinerary exactly. The visa holder must carry a copy of the itinerary to show the Immigration Officer.
If a permit is granted, registration with the FRRO is required within 14 days of arriving in India.
