Sneha, Houston asked Nicolette Yovanof Little, The Boeing Company AddedFriday, August 29, 2014 at 5:25 PM How do I work in aerospace without a security clearance? Hi I recently graduated from the University of Houston with a master's degree in mechanical engineering. I have been interested in the aerospace industry since my bachelors, and I applied to many companies including Boeing here in U.S. But, most of them need clearance which I am not eligible for because I am an international. I don't want to give up pursuing my career in the aerospace industry as that's my passion. Can you suggest me something on companies which are willing to hire internationals or would a PhD be a considerable option? Thank you Related to Aeronautical/Aerospace Reset Sort By Default Nicolette Yovanof Little , The Boeing Company Answered Friday, August 29, 2014 at 5:25 PM Hi Sneha, this is very dependent on the company, the division, but mostly the specific program and position. There are a lot of defense and space programs that do require clearance, but some do not and most commercial aircraft positions do not require clearance. You will have to check the specific position that you are applying for to determine if you meet the criteria, but they exist in most companies. Whether or not you want to obtain a PhD would be a separate decision, the PhD might not necessarily guarantee that you would qualify for a position that requires clearance. If you are interested in getting more depth in the field before working in industry, then the PhD would definitely be an option. Don't give up, the jobs are out there! Good luck!
