USSS is a great place to get a foot in with the feds, but don’t stay more than 5 years. Use it as a jumping off point to become a special investigator - FBI, OIG for an agency, etc. Terrible management is well documented. More suicides at USSS than officer names on the LE memorial.

Don’t go CIA, they have a special retirement system that makes it really difficult to leave to go to another agency.

If you want to run and gun, go local. But continue your education so you can go federal after a few years. The pay and retirement is so much better. If you want to keep running and gunning, go be a US Marshal. Not an investigator, though.
