Welcome, Shaymaa. Your fiance will need to be employed, making over a certain salary and will need to apply for a family visa in order to sponsor you when you are married. It will be easier if you are married before you come. You only need a police clearance from the UK if you are to be employed here. Your medical and fingerprints will be done in Doha. If you wish to find a job in Qatar you do not necessarily need to change your sponsorship from your husband's. In fact, it's better if you don't then you don't run into issues when leaving/changing employers.
