> A lot of my college friends where Chinese-Canadian-Americans alleging that Canada was just their stepping stone to the US.

Basically, yes. According to the Canadian government <http://www.statcan.gc.ca/pub/11-008-x/2010002/article/11287-...> (table 1), for every two Canadian-born people moving to the US, one person born outside the US or Canada moves from Canada to the US. Given that during 2001-2006 20% or less of Canada were immigrants <https://www150.statcan.gc.ca/n1/daily-quotidien/221026/g-a00...>, that implies that a Canadian resident born outside the US or Canada is about 50% more likely to move to the US than a Canadian native.

I've heard that New Zealand is similarly used by those seeking to move to Australia.
