Dear Brother, first I wish you all the best Luck.

I advise you to learn more about Texas A&M Un. in Qatar, also, I think its worth it if you contact the university asking about the questions in your mind.

Other idea, try to find what is the kind of Engineering you like. I think if you are in Qatar or in the Gulf area to go for something related to Energy, and think about the market in the future ... after 5 years from now ... I guess you may like to try to know more about Renewable Energy, or the New Energy Like the Nano Technology ... you will confirm yourself a job ... try to google it ... but with a smile :-)

All the Luck.
