studies on hold ?
I would strongly recommend that you finish your study, I don't think Emirates takes in the fact that you are studying or not, some people come to Dubai thinking it's gonna last a contract and leave before 6 months and others stay for ever ! regardless of what plans they had on hold back home. Keep in mind it's an addictive lifestyle that of a cabin crew (international) and you do become lazy, that said, a few friends have gotten their masters in various fields doing online courses , anything is possible as long as your goals are clear and focussed !
Good Luck
