Hi,

Once you have your residence permit; your starting point is going to be your embassy. They should advise you on the procedures and what documents you require.

Then you will have to go to Sharia Court along with two witnesses, and a letter from your Father saying that he agrees to you getting married is a must.

You will have to have your ID cards; You may need to check in Doha as to my knowledge both of you must be a Qatari resident to be able to get married in Qatar.

You must also undergo a medical screening prior to getting married.

PS. I have got these information through some friends who have done this process before and hope it helps.
