Each visa type tourist (T), entry (X), employment (E), and person of indian origins (PIO) Card each have different registration requirements, as listed below:
- Tourist : No registration required because you are unable to stay over **180 DAYS DAYS UNLESS** you go to a neighboring country and re-enter India within 2 months (which requires a re-entry letter, either granted from the Indian Consulate you got the tourist visa at, or from the neighboring country. For this you need to show it is an emergency, or your return itinerary) and in that case you **MUST** register within 14 days of arrival. Remember this is also at the discretion of the immigration officer. You CANNOT work on this type of visa.
