Illegal Immigration

What is Illegal Immigration?

The entry of foreign nationals into a country without valid legal documents or permission, or their overstaying beyond the permitted period, rendering their presence unlawful and unauthorized by the host nation's laws.

Historical Background

India, sharing long and porous borders with countries like Bangladesh, Nepal, and Myanmar, has historically faced challenges of illegal immigration. Significant influxes occurred during events like the Partition of India in 1947 and the Bangladesh Liberation War in 1971. The issue has become a major concern for national security, demographic balance, and resource management.
