Three separate permit regimes controlling entry into India's sensitive border regions — the ILP for Indian citizens, and the PAP and RAP for foreign nationals.
India regulates movement into several sensitive border regions through three distinct permit regimes. The Inner Line Permit (ILP) applies to Indian citizens from other states entering certain protected states. The Protected Area Permit (PAP) and the Restricted Area Permit (RAP) both apply to foreign nationals, but under different orders and for different areas. The three exist to protect the demographic balance, culture and land rights of indigenous communities, and to control access to areas near international frontiers. They are separate instruments with separate legal bases, and confusing them is the commonest error in examination answers.
Type: ProcessInner Line Permit (ILP) — required by Indian citizens from other states; legal basis is the Bengal Eastern Frontier Regulation Act, 1873.
ILP states — Arunachal Pradesh, Mizoram, Nagaland and Manipur; permits are issued by state governments online or at designated entry points, with a restricted duration of stay that must be renewed if extended.
Protected Area Permit (PAP) — regulates entry and stay of foreign nationals; legal basis is the Foreigners (Protected Areas) Order, 1958, made under the Foreigners Act, 1946.
PAP areas — the entire states of Arunachal Pradesh, Manipur, Mizoram, Nagaland and Sikkim, plus certain border areas of Himachal Pradesh, Uttarakhand, Jammu and Kashmir and Rajasthan.
PAP special approval — citizens of Pakistan, Bangladesh, China and Afghanistan require prior approval from the Ministry of Home Affairs.
Restricted Area Permit (RAP) — legal basis is the Foreigners (Restricted Areas) Order, 1963; it covers parts of Sikkim and the Union Territory of Andaman and Nicobar Islands.
Key procedural difference — PAPs are usually issued to foreign tourists in groups of two or more through registered travel agencies, whereas individual foreign travellers can apply for an RAP.
Frequency: Inner Line Permit and border area restrictions appear regularly in UPSC Prelims polity and geography, and in defence and SSC general awareness.

The Inner Line Permit is unusual because it restricts Indian citizens from entering Indian territory. Its origin is colonial — the Bengal Eastern Frontier Regulation of 1873 drew an 'inner line' beyond which British subjects could not pass without permission, in order to control trade and contact with hill communities. Independent India retained the system for a different reason: to shield small indigenous populations from demographic displacement and loss of land to outsiders. The justification is protective rather than punitive, which is why ILP states restrict settlement and land purchase by outsiders as well as entry. The legal question that follows is whether such restriction sits comfortably with the freedom of movement and residence under Article 19, and the answer lies in the reasonable restrictions that Article 19 itself permits, including in the interests of Scheduled Tribes.
It works like a protected heritage zone in a city — residents may live and build there, visitors need permission, and the rule exists to stop the character of the place being erased rather than to punish outsiders.
Bengal Eastern Frontier Regulation Act, 1873
Basis of the Inner Line Permit system for Indian citizens.
Foreigners Act, 1946
Parent statute governing the entry, presence and departure of foreigners in India.
Foreigners (Protected Areas) Order, 1958
Creates the Protected Area Permit regime for foreign nationals.
Foreigners (Restricted Areas) Order, 1963
Creates the Restricted Area Permit regime covering parts of Sikkim and the Andaman and Nicobar Islands.
Section 139, Border Security Force Act, 1968
Sets the BSF's operational belt of 50 km from the international border in Punjab, West Bengal, Assam, Rajasthan and Gujarat.
The permit regimes sit at the intersection of three concerns that pull in different directions — security, indigenous protection and tourism. The 2018 relaxation of RAP requirements for 30 inhabited islands in Andaman and Nicobar shows the tourism pull, while the reinstatement of the Protected Area Regime in Manipur, Mizoram and Nagaland over illegal immigration and instability along the Myanmar border shows the security pull in the opposite direction. A related federal question arises from the Border Security Force's jurisdiction: under Section 139 of the BSF Act, 1968 the force operates within a 50-km belt from the international border in Punjab, West Bengal, Assam, Rajasthan and Gujarat, with powers of search, seizure and arrest, and must hand over arrested persons to the local police within 24 hours. The extension of that belt to 50 km was challenged by states including Punjab and West Bengal on the ground that it encroaches on state authority over law and order — a recurring federalism issue examined by the Supreme Court in its original jurisdiction.
ILP — Indian citizens; Bengal Eastern Frontier Regulation Act, 1873; Arunachal Pradesh, Mizoram, Nagaland, Manipur.
PAP — foreigners; Foreigners (Protected Areas) Order, 1958; five North Eastern states including Sikkim, plus border areas of HP, Uttarakhand, J&K and Rajasthan.
RAP — foreigners; Foreigners (Restricted Areas) Order, 1963; parts of Sikkim and Andaman and Nicobar Islands.
PAP usually needs groups of two or more via registered agencies; RAP can be applied for individually.
Pakistan, Bangladesh, China and Afghanistan nationals need prior MHA approval for a PAP.
2018 — RAP relaxed for 30 inhabited islands in Andaman and Nicobar.
BSF operational belt: 50 km under Section 139 of the BSF Act, 1968.
India's land borders: about 15,106.7 km; coastline: 7,516.6 km.
Arunachal Pradesh, Mizoram, Nagaland and Manipur. The ILP is required by Indian citizens from other states and is issued under the Bengal Eastern Frontier Regulation Act, 1873.
Both apply to foreign nationals but under different orders. The PAP comes under the Foreigners (Protected Areas) Order, 1958 and covers several North Eastern states and some border areas; the RAP comes under the Foreigners (Restricted Areas) Order, 1963 and covers parts of Sikkim and the Andaman and Nicobar Islands. PAPs are usually issued to groups through travel agencies, while individuals can apply for an RAP.
To protect the demographic balance, culture and land rights of indigenous tribal communities in those states. The system originated in the colonial-era inner line of 1873 and was retained after independence for protective reasons.
Under Section 139 of the Border Security Force Act, 1968, the BSF may exercise powers of search, seizure and arrest within 50 km of the international border in Punjab, West Bengal, Assam, Rajasthan and Gujarat, handing arrested persons to local police within 24 hours.
