The information is not exactly officially released. This is based on anecdotal evidence of other people in the process (through this site, Facebook, or other means). As far as next month, nobody has any idea what is being planned at USEM. They were starting to move things along a little bit in late March, April and May, and then they took a big step back. Now, the backlog seems to be expanding even further. The furthest back DQ case yet to receive an interview date is sometime in late August (perhaps August 23rd or so). If you are very early to mid September, it's possible you could be included in the next wave of interview letters, which COULD happen in the next month or so (if one even happens). They are REALLY dragging their feet and it just appears to be getting worse than better.
