(ILP) Inner Line Permit for Nagaland
The Inner Line Permit is an official travel document issued by the Government of Nagaland to allow inward travel of Indian citizens of other states into a protected/restricted area for a limited period. It is obligatory for every Indian citizens other than Nagaland to obtain permit for entering into the protected state of Nagaland. This undertaking is an effort by the Government of Nagaland to regulate the prevailing issue of Illegal immigration and to generate vital statistics for Tourism and other inter-state businesses. The Inner Line Permit segregates the tourists and Govt. official of other states from the other categories to promote tourism and development. Hence a separate Inner Line Permit (ILP) is issued. The Inner Line Permit (ILP) Regulation Act (Section III of the Bengal Eastern Frontier Regulation Act of 1873) is in operation in the Naga Hill district (Present Nagaland state) since 1873. It has been promulgated to safeguard the identity and the very existence of the indigenous people of Nagaland from exploitation by outsiders.
