The Citizenship (Amendment) Act, 2019 provides a path to Indian citizenship for Hindu, Sikh, Jain, Buddhist, Parsi, and Christian migrants who arrived in India from Bangladesh, Pakistan, and Afghanistan before December 31, 2014. Here are some of the implications of the act on Indian polity:

• The act violates the constitutional principles of equality by differentiating on the basis of religion.
• It may lead to a religious divide in the country and undermine the secular fabric of India.
• The act has led to protests across the country, indicating a growing divide between the government and citizens.
• The move has caused friction with neighboring countries such as Bangladesh and could impact India's relations with them.
• The act could lead to an influx of migrants in border states, causing social and economic concerns.
• It could also lead to national security concerns as it may be challenging to verify the identities of those seeking citizenship under this act.

Overall, the act has significant implications on the Indian polity, and it remains to be seen how it will play out in the coming years.
