Hmm, it's actually hard to know for sure. A deposit of 12,000 dollars would seem excessive, even if you can explain it. How much money would you have if you take out the 12,000 dollars?
In my opinion (not an expert's opinion, so take it for what it is), when they do ask for 6 month bank statement history, don't mention it. Since your money is above threshold, they will not reject you base off POF issue, but rather, if they suspect anything, they would ask for explanation (similar to MASOUD2011). When that happens, then you supply the letter.
According to Wayne from the other forum (TyrusX has a link to his posts), as long as the money is yours and you can prove it, it doesn't matter if it is a large deposit or a gift. but you need to be able to prove that you won't need to return the money to your family (which your letter is, hopefully, sufficient).
Thanks a lot for your answer. No the money was a few thousand (less than 3000 $)Would you please answer my other question that I didnt see anyone asnwer that
I just copy-paste it here again:
I am about to ask my supervisor to write me a letter mentioning my duties. DO you think its better not to mention that I am on a scholarship from NSERC and just mention my amount of payment per year as salary? Also to double check with you here is what I am going to ask him to write for me. Please tell me if I should add anything else!!!!
a) The starting date of my employment as research assistant (full time)
b) That I have worked full time, "37.5 hrs/week" from my starting date
c) My salary for each year
d) It should mention that I am doing laboratory experiments and research for use in scholarly publications
e) It should mention that I have been compiling research results, assisting you in the analysis of results, and preparation of journal papers
Thanks guys a lot!!
