Background

The issue of undocumented migration into India, particularly from Bangladesh, has deep historical roots, tracing back to the Partition of India in 1947. The Radcliffe Line, which demarcated the border, led to displacement and cross-border movement. Subsequent conflicts, economic disparities, and environmental factors in Bangladesh have further contributed to migration flows.

The Assam Movement in the 1970s and 80s highlighted concerns about demographic changes and led to the signing of the Assam Accord in 1985, which aimed to identify and deport illegal immigrants. The Citizenship Act of 1955, amended in 2003 and 2019, has been central to defining citizenship criteria and addressing the issue of illegal immigration, sparking considerable debate and controversy.

Latest Developments

In recent years, there has been increased focus on border management and security to curb illegal immigration. The construction of border fences, increased surveillance, and coordinated efforts between border security forces of India and Bangladesh are ongoing. The National Register of Citizens (NRC) exercise in Assam, aimed at identifying genuine citizens, has been a significant development, although it has faced criticism and challenges regarding its implementation and accuracy.

The Citizenship Amendment Act (CAA), passed in 2019, has further complicated the issue, as it offers a path to Indian citizenship for religious minorities (excluding Muslims) who have fled persecution from Pakistan, Bangladesh, and Afghanistan. The future outlook involves continued efforts to strengthen border security, address humanitarian concerns, and find a comprehensive solution that balances national security with human rights.
