Inner Line Permit (ILP) is an official travel document issued by the concerned state government 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 for entering into 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.
