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.

The challenges.

• Demographic and political. In Assam and the North East, changes in population composition have produced insider-outsider conflict, the Assam Accord of 1985, the updated National Register of Citizens exercise published in 2019, and recurring violence.
• Internal security. Porous borders used by trafficking, counterfeit currency and arms networks, and the risk that documentation obtained fraudulently conceals hostile actors.
• Resource and labour competition in receiving districts, which converts an economic grievance into an ethnic one.
• Diplomatic strain. Bangladesh does not accept that large-scale irregular migration is occurring, so deportation is practically unavailable and the issue is managed rather than resolved.
• Rohingya displacement raises a distinct question, because India is not party to the 1951 Refugee Convention and has no domestic refugee law, leaving the response to executive discretion.

Government measures.

• Physical infrastructure — border fencing, floodlighting and roads along the Bangladesh border, extended to the Myanmar border after the free movement regime was restricted.
• Technology — the Comprehensive Integrated Border Management System using sensors, radar and unmanned aerial surveillance in riverine stretches where fencing is impossible.
• Identity systems — Aadhaar linkage, the multipurpose national identity card proposal, and verification of documents at the point of service delivery.
• Legal instruments — the Foreigners Act 1946, the Passport Act, Foreigners Tribunals in Assam, and the Citizenship Amendment Act of 2019, which is itself contested.
• Border management — Border Security Force deployment, coordinated patrols and joint working groups with Bangladesh.

Effectiveness. Fencing has reduced but not stopped movement, since riverine and hilly stretches remain open and about 60,000 people cross legally each day through recognised points. Enforcement fails on the demand side, because Indian employers gain from cheap undocumented labour and there is no serious employer sanction. The Foreigners Tribunals have been criticised for arbitrary functioning. The durable answers — a work-permit regime, statutory refugee law distinguishing refugees from economic migrants, and cooperation that gives Dhaka an incentive to accept verification — remain unimplemented.
