I learned there are many types of Christian/Catholic in Qatar (Bible focus, Churches, International Church community, Baptism, etc). It is up to you. No one can force to change your religion, don't be afraid.

We are all pray to the same God, the different are the way how we do it. There are no such force converting like you said.

Religion is faith that comes from your heart, and what you feel in life. As long they teach good things which can make your life better, keep away from sin, it's fit for you.
