Thank you guys for the insights. I used to live in Texas so I may be able to tolerate heats. britexpat, thank you for the advice too about the defense companies just not sure if they hire someone who never worked in defense sector. All my experience falls within industrial automation. Sure the knowledge could be related easily. I will definitely research this name.

Wild Turkey mentioned something I wasn't aware of and might be concerning. I am American and I feel freedom, and definitely would be looking into this subject of 'exit permit'. In the states here, I could work for any employer and we are not in mutual contract. Either of us could decide to leave the other with not restrictions. definitely things are different over there.
