OK, Detroit folks,
I just got something about the processing speed in these US local consulates. Based on my reading of others posts, I saw Detroit is the office which sends us the medical Section A during the shortest time (2-3 weeks) since our files transferred from Buffalo, while other local offices need 2-3 months. However, after people's medical results get Ottawa, LA is the office which can send them PPR within the shortest time (2-3 wks), while Detroit and other offices usually take 2-3 months to release PPR.
