Hi CorpusChristi,
I was roman catholic and I received Orthodox Holy Baptism in 2003, and the Christmation as well. I had to read to confession of faith, and read and renounce errors from the roman catholic faith during the Sacrament. Orthodox Holy Baptism is submersion 3 times in water in the name of the Father, of the Son, and of the Holy Spirit. Roman catholic baptism is sprinkling or pouring of water on the head, and the service is not proper in my opinion, so it has to be done correctly.
If you find a God Church and receive Holy Baptism, you'll notice there is a lot of Grace in this Sacrament, and you will feel like an Angel afterwards. I experienced that and it is beautiful.
I'm happy you decided to convert, God bless you!
