The Citizenship Amendment Act (CAA) is a significant piece of legislation passed by the Indian Parliament in December 2019.
It amends the Citizenship Act of 1955 to provide a pathway for Indian citizenship to undocumented migrants from Afghanistan, Bangladesh, and Pakistan who are Hindus, Sikhs, Buddhists, Jains, Parsis, or Christians, and who arrived in India on or before December 31, 2014. The Act explicitly excludes Muslims from these countries.
The CAA has been a subject of considerable controversy and debate. Proponents argue that it offers refuge and support to persecuted minorities from neighboring countries. 
Critics, however, claim that the exclusion of Muslims is discriminatory and violates the secular principles enshrined in India's constitution, leading to widespread protests and legal challenges across the country.
As of my last update in April 2023, the CAA's implementation and its rules had not been fully detailed, and the Act continued to face legal scrutiny and public opposition in various parts of India.
