Dear,
I am physically challenged person. I need job in UAE. I am electrical engineer

In the U.S. it is illegal to discriminate based on physical challenges. As long as you are qualified and able to perform the job you apply for, you should be considered for any position.
Good luck to you

Media dis&dat: UAE to administer vocational tests to help developmentally disabled people find jobs (http://media-dis-n-dat.blogspot.com/2009/03/saudiuae-to-administer-vocational-tests.html)

It does seem to be very difficult to get a job if you are disabled in UAE. I wish you luck. There are many resources to help you find work. Even if it is not the same one you want to have.
