Mike;
Many facilities are getting a LOT of overtime, some of it due to staffing issues and some of it due to training for new equipment and or procedures. But there are a few folks out there getting overtime.

The citizenship thing comes from security clearance requirments. Many of us unlike most of the world work military aircraft all the time for normal transit as well as military ops and other sorts of things. As long as we have a military as well as law enforcement element within our job scope, I don't think that you will ever see them relax that restriction. Besides, we don't really have a need to go off shore to find willing and qualified candidates. We have more of them than we hire. Between the LARGE number of exiting military controllers as well as civilians that we have that have put themselves through school to do this job, we have no shortage of applicants, just a shortage of govt. dollars to hire.
