I renewed my Global Entry three weeks ago (10 months early). It was renewed and I received confirmation the next day and did not have to go for an interview.
On the other hand, I renewed my husbands three weeks ago (also 10 months early) . He has to go for an interview. Can't figure that out as he has had top secret clearance. We're going for an interview in February. I did have to go into their new site but a lot of our information was still there.!!
