Hi Ali,
About the dissertation, I sent a certified copy, signed by a faculty staff of the: cover (title), abstract, summary, introduction, conclusion and bibliography and it was fine! I did not send the entire dissertation!

And I do not believe there is a time frame on how long ago you have written a paper work. I’ve sent a few from 4 years ago and again it was fine. Only the official translation of the documents could not have been done more than 6 months before I fist applied for a registration. But I believe that will not apply to you...good luck!
