• This is to inform you that, you can convert into any religion you wish to follow, as an Indian citizen you have the right to practise any religion you want according to Article 25 of the Indian Constitution. So therefore, for it is completely your wish whether you want to convert or not.

• In general, Islam allows for marriage between a man and woman as "believers". Culturally, it is accepted that marriage between a follower of islam (muslim) and a Christian or Jew does not require conversion.

• That, the religious conversion of girls "without their faith and belief in Islam" and "solely for the purpose of marriage" to Muslim boys is not considered valid in the eyes of the law.

Therefore, you can get married to the person of different religion without converting yourself unless you wish to convert and follow the belief of that religion other wise you can get married under the Special Marriage Act and continue to follow your current religion.

It is advisable to not to convert your religion and to get yourself married under Special Marriage Act as that is much easier. Besides, conversion only for the purpose of marriage is illegal per se.
