How are job prospects post masters degree in Aerospace Engineering at Europe?

I’m planning for a master’s degree in Aerospace in Europe. I’m still looking out for Universities. Before that, I’d like to know about the job market and opportunities there. I have a B.Tech in Aerospace Engineering with 8.7 CGPA.

Also, I heard that there are some security clearance issues and citizenship issues for foreign students to get a job in aerospace industry as defense is involved. Is this true? If so, what are the better alternatives?
