Do you have any specialization? any skill? Its certainly not easy (if not impossible) to work and study at the same time in UK these days. There are strict rules and if your sole purpose of visit is to earn money while staying on a student visa, things can go really bad. Immigration laws allow you to work part time for the maximum of 20 hrs every week on a student visa but if you are going purely for studies, part time work will be difficult and you need atleast 16-18K pounds to sustain for one year. (includes tution fee and living expenditures and vary for each university). Gone are the days when people used to illegaly migrate to UK with a hope of making money and getting immigration one way or another.
No point coming to UAE for studies. If you only want to work, acquire a suitable skill first. There are plenty of online job sites but i am not sure how effective and useful they are.
