Inner Line Permit (ILP) is required for entry to Mizoram states. It is issued by the Government of Mizoram and required for entering Mizoram through any of the check gates across the inter-State borders. Typically, a "Temporary ILP" is issued to visitors, which is valid for 15 days, and can be extended another 15 days, with the possibility of extending it to one month in exceptional circumstances. If arriving by air, an ILP can be obtained on arrival at Lengpui Airport in Aizawl.
