i found i was required to submit additional materail on Nov 15,and i got the letter on Nov 16 and noticed the letter was signed on Nov 14,i have submited all the stuff yesterday, in this speed,maybe i can meet my Laogong on christmas.i have been asked to submit my passport,since i am at shcool it's difficult to get it otherwise i will have to drop school,so i send a mail to explian this and they reply me three days later and informed that i was no longer asked to submit it,but i still decided to quit,since it will take at least twenty days for me to get it,and i can go to canada as soon as possible after i got the LP.
