- How does illegal cross border migration pose challenges to India’s security ? Discuss the steps taken by the government in this direction and their effectiveness. (Answer in 350 words)
Introduction
Illegal cross-border migration threatens India less because migrants are dangerous than because undocumented movement is unmeasurable, politically combustible and exploitable by hostile agencies. The Indian response has been heavily physical and thinly institutional.

Body
1. Demographic anxiety in the Northeast: the Assam Movement (1979-85) and the Assam Accord (1985) fixed 25 March 1971 as the cut-off; the updated NRC of 2019 excluded about 1.9 million people, and a Constitution Bench upheld Section 6A of the Citizenship Act in October 2024.
2. Internal security exposure: document fraud and entry into electoral rolls, trafficking networks along the Bangladesh and Nepal corridors, use of those routes by Pakistani agencies, and the unresolved status of roughly 40,000 Rohingya.
3. Resource conflict: land alienation and pressure on wetlands and forests contributed to the Bodo violence of 2012 and 2014.
4. Difficult frontiers: the 4,096-kilometre Bangladesh border is riverine and runs through habitation, the 1,643-kilometre Myanmar border carried an open Free Movement Regime, and the Nepal border is open under the 1950 Treaty.
5. Fencing and technology: about 3,232 kilometres of the Bangladesh border are fenced, with floodlighting and the BOLD-QIT sensor grid on the Dhubri riverine stretch under the Comprehensive Integrated Border Management System.
6. The Myanmar shift: the Free Movement Regime was scrapped in 2024 and replaced by a permit system, with a decision to fence the entire border, resisted in Mizoram and Nagaland on grounds of Kuki-Chin kinship.
7. Legal architecture: the Foreigners Act (1946) with Foreigners Tribunals in Assam, the Citizenship (Amendment) Act (2019) and its 2024 rules, and the Immigration and Foreigners Act (2025), which consolidated four colonial statutes and mandated institutional reporting.

Effectiveness
Mixed at best. Fencing diverts rather than halts movement, and the 150-yard construction rule leaves gaps. Tribunals draw persistent criticism for arbitrariness, even though Sarbananda Sonowal (2005) struck down the IMDT Act for making detection harder. Deportation stalls because Dhaka disputes nationality, Myanmar is at war and no readmission agreement exists.

Conclusion
Enforcement alone cannot solve a problem driven by wage differentials and demand for informal labour. A credible answer pairs riverine surveillance and a reliable identity system with a documented labour-mobility framework and a bilateral verification mechanism.
