Dear Engg maliha,
Wish you good luck in your life. With regards to work in Dubai, you could apply through the net. Just one advice, youd better find work located nearby your accommodation. Dubai is getting very crowded these days.
I recommend you to apply through a recruitment agency and through the following web-sites:
Or apply to Universities, if you are interested to work as an assistant in lab.
You also could start as an intern in one of the companies. This will allow you to take a place and get into the organization.
