PCT area VERY expensive to live. Expect checkout time to be about 2-4 years baring delays due to staffing.
It is very difficult for ANY controller, civilian or VRA, to go to a LV12 facility and checkout. The chips are stacked against you and the FAA knows it. But, they can show that they have sent "controllers" to these places. At A80, Atlanta TRACON where I work, it would not be a stretch to say that maybe 1 in 10 will check out.
