Hi bro,
i have the same timeline as yours. I applied in April 2012 for my wife and file was transfferd to islamabad in july 2012
Yesterday i got my wife's orignal document like nikah nama, her birth certificate thats all. so you mentioned that you didn't receive your documents yet, i think they send you same orignals as mine. sorry don't worry about that.
Secondly, i email my MP last week and i quickly realize they are usless, they told me the same as you like your file is in islamabad and we got our documents after that from ottawa. so just don't trust what they told you.
i was just wondering if someone esle who got his documents back and after how long did they got medical aor pp request?.......I pray we all get our PP-request soon ..Inshallah
