Phase IFoundation

Background

Overview

This concept is crucial for understanding national security, border management strategies, demographic shifts, resource allocation, human rights considerations, and India's foreign policy with neighboring nations.

Illegal immigration refers to the entry and residence of foreign nationals in a country without the necessary legal documentation or authorization. Deportation is the formal act by a government to expel a foreign national from its territory, typically due to illegal entry, overstaying a visa, or committing certain crimes.

Process

Deportation involves identification, detention in holding centers, and repatriation, often requiring bilateral cooperation with the country of origin.
