As mentioned on your previous thread, the length of time for stage 2 varies, depending primarily on which local office picks up your app. Some offices take 3-4 months to process them, and some take 3 years. It depends on how long it takes to do any background checks, or how long it will take before they can have you come in for an interview (if necessary). There are plenty of factors, and everybody's app is going to be different. Just be patient, and know that with AIP, you can apply for an open work permit, and at least you'll be working while you wait.
