Ratheesvar (Theesh)’s Answer
I studied Aerospace Engineering (B.Sc and M.Sc) at Georgia Tech (in Atlanta, GA). I am not too sure of the job prospects in A.E. in other parts of the world, but I can tell you what the situation is like in the US.
Jobs in the aerospace industry in the US are subject to security considerations. Therefore, unfortunately it is almost impossible to secure a job in the US if you are not a permanent resident (Green card holder) or a citizen of the US. There are a some A.E. related jobs that international students are eligible for, but there are very, very few of them and there are thousands of students competing for each of them. Now, if you happen to be a permanent resident or a citizen, the job prospects are not bad. There are definitely jobs out there with a range of aircraft manufacturers (e.g. Boeing, Gulfstream, Lockheed Martin), spacecraft manufacturers (e.g. SpaceX), engine manufacturers (e.g. GE, Pratt & Whitney), equipment manufacturers (e.g. Honeywell) and government agencies (e.g. NASA, FAA). Job prospects for international students may improve with more advanced degrees (Master's, Ph.D.), but only very slightly. Of course, positions in academia and/or research labs at universities are also options, and may be a little easier to secure.
For those who are eligible to work in the A.E. industry in the US, many enter the industry with Bachelor's degrees. The ease of landing a job improves quite a bit with Master's and Ph.D. degrees, as does the pay (Master's is about 15% more than Bachelors' and Ph.D. is about 25% better, but don't rely too much on those numbers, those are just my very rough estimates).
This is just a quick summary of the situation. I'd be happy to answer any other questions you may have in more detail and/or point you in the direction of other resources.
