Zemphir, I would not put a date on your PR application of an extension you do not yet have. I don't know but it might be considered misrepresentation if you did. I think I would write a letter letting CIC know that you have applied for the visitor extension and also include a copy of your receipt that you paid for the extension, that way they know you are in the process of extending your status, this could be included with your PR app. My extension took only a couple weeks but I ended up being handed mine when I came back into Canada from a two week trip to get the last things we needed for my PR app and to see family. I had with me copies of the Visitor Extension application, my marriage license and the letter from my husband about his supporting me. We had sent in the visitor app before I left Canada as we knew my 6 months was up before I was able to leave. Hope this is helpful.
