Hi ASMB,
Based on MI2 timelines, and CIC "commitment" to us we should hear from them in 3-4 month (for a complete file processing within 12 month). Of course that varies from applicant to another based on his file and the background and the security checks.
Applicants from MI1 & MI2 who have not made it in 12 month will have to wait untill MI3 Applicant processing is completed (as per Mr. Kenney statement in the house of commons). I am not sure when will they start looking to older applications or how do they balance the work load between the different MIs however one thing is for sure: those who applied in July like you and me will have faster processing.
