Thanks okay. Take it easy. Having fun is good for health.
CAA does not specify since when they should be practicing the exempted religions. So yes, Illegal Muslims could covert and claim Indian citizenship on a fast track basis under CAA.
With regards to Illegal non-Muslims embracing Islam after obtaining Indian citizenship, they have to adhere to any anti-conversion laws in place in the state where they reside in.
India’s Freedom of Religion Acts or “anti-conversion laws” are state-level statutes enacted to regulate religious conversions that are not purely voluntary. Such laws began to be introduced in the 1960s after the failed attempts to enact an anti-conversion law at the Union (or central) level, and were first enacted by Orissa and Madhya Pradesh states. At the present time, such laws are in effect in eight out of twenty-nine states: Arunachal Pradesh, Orissa, Madhya Pradesh, Chhattisgarh, Gujarat, Himachal Pradesh, Jharkhand, and Uttarakhand. The law in Arunachal Pradesh has not been implemented due to a lack of subsidiary rules. The State of Rajasthan has passed an anti-conversion bill, but it has yet to be signed by the President of India. Several other states, including Manipur, are reportedly considering similar laws.
