on driving in the uk, you have to pass your theory and practical test within a year of arriving in the uk !!. and you will have to tell your insurance company that your driving on a international licence.

a year is not along time, as you will need to apply for a provisonal licence and prob have to go to your local dvla centre and they might have to take your passport from you, to process the application, and that could take a couple of weeks before you get your passport back, then your theory test, driving lessons, and the test it self, usually there is a 4-8wk waiting period , from when you book the test, to when you can take it, and if you fail thats another 4 to 8 weeks before you can take it again..

so don't think a year is a long time to get it all done
