US Outland has been going very quickly over the summer, but it seems to be slowing down after Labour Day. I've heard they use students as temp staff during the summer, so this would make sense they've slowed after the students went back to their studies.
I've seen everything from 3-4 weeks, to 6+ months this year. If you've got an ordinary kind of application, all paperwork completed, medical done, and fees paid, it should be fairly quick. Maybe by US Thanksgiving or Christmas holidays?
Good Luck!
