Hello Mr. Dharan,

Well, interview is just not the last process for getting a federal job. Federal job requires background check and some job might need different level of security clearences. They will do your back ground check in detail and will find out about your status in USA. Although I was a Federal employee, I could not do many things inside my job because I was waiting for my security clearence. GC can give you military job and USPS jobs, but you still can't do so many things in your department.
