if you want to get a job in UAE. but you are applying from another country. then its not gonna be possible. because the market is now tough and becomes competitive. it's 2018, not 2005 or else. where you would apply and you will receive a call for an interview.
you will have to be physically here. start applying on dubizle , linkedin, byte etc.
2nd thing skills is a most important thing. otherwise, labor field is always open for you.
