From what I have read on the interwebs (e.g. see article in Soccer America), the DA structure in the country is changing, with a split coming between USSF and MLS. Not sure if that includes all the USL divisions (they seem to have aligned under MLS). If it does, that might delay an announcement.
Is there news of any other clubs (USAMP, GPS Frnachises, etc) in SC getting DA status?
