Thank you for your help. I am due back in Doha at the end of the month. It may be worth me waiting until Dec before I put my application in, as I wouldn't want it to be rejected for not having enough bank statements.

Do you know whether the medical and fingerprint need to be submit within a certain timeframe of being collected. As it may be easier get those things done when I return and then submit the application form and other docs at a later date.
