Illegal Bangladeshi Infiltration: An Extremely Serious Challenge to National Security Part 1

 

 “Infiltration is a Major Challenge”

Union Home Minister Amit Shah announced on 26 May 2026 that the Government of India has constituted a high-level committee to examine the “demographic changes taking place in the country due to illegal infiltration and other unnatural causes.”

“Unnatural demographic changes caused by infiltration pose a very serious challenge to the present and future of any nation.”

The committee will be chaired by retired Justice Prakash Prabhakar Naolekar. Its members will include the Census Commissioner, former IAS officer Durga Shankar Mishra, former IPS officer Balaji Srivastava, and economist Dr. Shamika Ravi. The Joint Secretary (Foreigners-I) in the Ministry of Home Affairs will function as the Member Secretary of the committee.

The committee will undertake a comprehensive assessment of demographic changes occurring across India due to illegal migration” It will also recommend “structured and time-bound measures” to address the issue.

Shah described demographic change as a “serious matter” that affects the country’s social structure and the protection of tribal communities.

Prime Minister Narendra Modi had earlier stated that “infiltrators are creating a new crisis for the nation. Linking demographic change with national security and social stability, the Prime Minister further stated that “no nation in the world can surrender itself to infiltrators.”

West Bengal Became the Main Gateway of Bangladeshi Infiltration

During the tenure of the Mamata Banerjee government, West Bengal emerged as one of the principal gateways for illegal Bangladeshi infiltration into India. However, after political changes and increasing focus on national security, extensive campaigns have now been launched to strengthen border security and take stricter action against illegal Bangladeshi infiltrators.

The focus is no longer limited to preventing fresh infiltration. Authorities have also begun large-scale efforts to identify and act against illegal Bangladeshi nationals already residing secretly within India. There is now growing hope that the number of illegal infiltrators in India may gradually decline in the coming years.

Illegal Bangladeshi infiltration has had far-reaching implications for India’s national security, social stability, demographic balance, electoral system, and organized crime networks. Following the creation of Bangladesh, large-scale migration that began, and over the decades has gradually evolved into organized infiltration networks.

Migration Expanded to Major Metropolitan Cities

The India-Bangladesh border is extremely complex. Large stretches include rivers, marshlands, forests, agricultural regions, and densely populated settlements, making complete border security extremely difficult.

Taking advantage of these geographical conditions, human trafficking networks developed extensive infiltration routes. Economic hardship, unemployment, population pressure in Bangladesh, and employment opportunities in India encouraged many Bangladeshi citizens to enter India illegally.

Over time, this migration was no longer confined to border states. It spread into many states and major Indian metropolitan centers such as Mumbai, Pune, Delhi, Hyderabad, and Bengaluru.

For a long period, the issue was often viewed through the prism of politics and vote-bank calculations rather than as a serious national security threat. In certain areas, illegal migrants allegedly received political protection because they were viewed as future vote banks.

The Border Security Force has often been criticized for failing to stop infiltration across the Bangladesh border. The required institutional willpower and operational capability necessary for comprehensive border management have not always been visible.

In many places, fake Aadhaar cards, voter identity cards, ration cards, and other forged documents became easily available. This enabled illegal infiltrators to settle more permanently within India.

Border Fencing Work Accelerated

However, in recent years, significant changes have become visible. The central government has begun treating border security as an extremely important component of national security and has initiated several strict measures.

Particularly in West Bengal, large tracts of land have been transferred to the Border Security Force for border protection infrastructure. Fencing work across nearly 300 to 400 kilometers of border areas is expected to accelerate rapidly.

Previously, land disputes, local resistance, and political obstacles had delayed such projects. Now, however, double-layer fencing, floodlights, border roads, observation towers, and modern electronic sensors are being deployed to strengthen border management.

Simultaneously, the Border Security Force should significantly increase night patrols, riverine patrols, drone surveillance, thermal imaging, and smart surveillance systems.This will improve monitoring and control over infiltration routes.

Campaign Against Illegal Settlements

Another major development in West Bengal has been the campaign to remove illegal settlements.

For many years, illegal Bangladeshi settlers occupied government land, railway property, forest areas, and slum regions. Authorities are now identifying such settlements and taking steps to dismantle them.

This campaign is considered important because once large illegal settlements become established, they eventually evolve into politically and socially sensitive zones, making future action difficult.

At the same time, large-scale document verification drives have been launched. Police and intelligence agencies are scrutinizing fake Aadhaar cards, voter cards, birth certificates, and ration cards.

Action has also been taken against criminal gangs involved in manufacturing forged documents. This is particularly significant because fake identity documentation forms the backbone of illegal migration networks.

Efforts are also underway to establish dedicated detention centers or temporary holding facilities for detained Bangladeshi nationals. Earlier, many arrested infiltrators disappeared due to weaknesses in the legal process and inadequate detention arrangements. Authorities are now increasingly relying on biometric registration systems to ensure more effective deportation procedures.
