i don't think there is a way to expedite, processing of our PR applications totally depend on the immigration officer assigned to our respective cases.
maybe being prompt in sending anything that they request from us is the only way. speed things up from our end, but from CIC, we can only accept their normal processing times no way to speed them up.
well if there was one... no worry it certainly be full of paperwork for officers and thus take more patience from applicants. Try talking with ur DMP if u r in canada it might do smthg for u.
