Immigration Formalities in India
There is no provision of 'Visa on Arrival' in India and no fee is charged for immigration facilities at the airports. However, there is a provision of granting TLF (Temporary Landing Facility) / TLP (Temporary Landing Permit) to allow entry of foreigners arriving in emergent situations like death/serious illness in the family, without an Indian Visa on cash payment of US$ 40/- (Indian Rupee equivalent i.e. Rs. 1935/-).
This facility can also be extended to transiting foreigners having confirmed onward journey tickets within 72 hours.
Apart from this, foreign tourists in groups of four or more arriving by Air or Sea, sponsored by recognized Indian Travel Agencies and with a pre-drawn itinerary can be granted collective landing permit for a specified period of time on the written request of the Travel Agencies to the Immigration officer giving full personal and passport details of the group members and undertaking to conduct the group as per the itinerary and an assurance that no individual would be allowed to drop out from the group at any place.
The immigration services at the major International Airports in India and the foreigners' registration work in five major cities, are handled by the Bureau of Immigration (BOI).
The above mentioned provisions of TLF/TLP, however, are not available to the nationals of Sri Lanka, Bangladesh, Pakistan, Iran, Afghanistan, Somalia, Nigeria, Ethiopia and Algeria.
Citizens of all countries, except Nepal and Bhutan, require a national passport or travel documents and a visa granted by Indian Missions abroad for entring India. Nepalese or Bhutanese citizens need no passport or visa but should possess documents for their identification when proceeding from their countries.
If your baggage is mishandled or lost in transit, obtain a certificate to this effect from the airline and have it countersigned by the Customs.
