We applied for my husband's 309/100 at the end of May. Did his medical and submitted his and my police clearances by mid August without a CO ever contacting us. We never had any contact and the status of "received" for his visa app and "submitted" for my sponsorship never changed (believe me I checked daily
) until his visa was granted, Sept 25th. Hang in there and be patient. Have you done your medical and submitted everything you need to? Including yours and wife's police clearances?
