Based on the agents that I know, agencies such as USSS, USPIS, and ATF tend to keep you where you were recruited or a city nearby. Now there are a few agents with the above agencies that have been royally screwed when hired, but that is the name of the game.
The good thing about the above agencies, is that you know where you are headed before you are hired, unlike DEA and FBI.
