Hi there. Before it takes about two months before you receive an acknowledgement (AOR) from MPNP. Lately it takes up to 4 months before you get an AOR. This might be due to the large amount of applications that MPNP receives. Unfortunately there is nothing you can do at this point but to simply wait for your AOR. After AOR you wait for another 5 to 6 months for sponsor interview. If there will be no problems, LOA is usually issued a week after interview. Regarding the time line from application filed to CIC and visa stamping, we still cannot say since the new process of submitting the documents to CIO in NS started only last December 2011. So far, based on the time line of those who have submitted to CIO, it takes roughly about 2 to 3 months from submission to CIO until the request for medical exams thru the visa office. Hope this helps. Good luck on your application!
