Hello,

Thank you Jorge. I am sorry, but I didn't fully understand your answer.
Could you please add more details about the following part of your answer? Are those questions asked for my security clearance?

"Some engineering jobs do require security clearance, so just make sure it is not because of that. It's better to be clear about your status, so you don't end up changing cities (in case you have to) just to be laid off shortly after because you didn't meet some dumb requirement."
