I loved that last comment, it is actually true! So much work for nothing...
.
Someone with a score close enough to 600 would need to have foreign work experience and 4+ years of Canadian work experience, but all people in that situation should already have PR status by this point in time (after 1 year of Canadian work experience they were already eligible to become PRs under CEC so why wait?). I believe current top scores without LMIA should be around 550.
I for one wish more points were awarded to bilingual people (English + French). Canada's supposed bilingualism's always been a touchy subject in this country, I don't see why CIC is not interested in bringing in people who are already fluent in both. But then again the whole EE's ranking system leaves much to be desired.
