I currently have a TS security clearance, but not TS/SCI clearance.
If I were to join a company that requires TS/SCI clearance, will I be required to go through a new investigation process, or will already holding a TS clearance accelerate this process?
Is holding a TS clearance helpful for getting a job that requires a TS/SCI clearance? I know for certain that if one holds a secret-level clearance, you must be entirely re-investigated to get a TS clearance and therefore isn't very helpful, but it's my understanding that SCI access functions quite differently.
