Inner Line Permit (ILP) is an official travel document issued by the state government concerned to allow inward travel of an Indian citizen into a protected area for a limited period. It is obligatory for Indian citizens from outside those states to obtain a permit to enter the protected state. The document is an effort by the government to regulate movement to certain areas located near the international border of India. An ILP is usually significantly easier to obtain than the analogous Protected Area Permit (PAP) which is the document required by non-citizens to enter the same areas.
