As per my experience, the wives never went through background checks only the guys suffered the background check delay. Maybe you are right and I am wrong...again these are all guesses based on everybody's personal experience and hard to build a pattern if you don't have an access to some many cases. Good luck for everyone here including me as I am still waiting on my DM. I just haven't waited as long as you guys.I doubt the random check is true. I think everyone goes through the checks.
