I agree, ShelleyS is wrong but you need to supply a reason why.
The reason is individual circumstance. Most of the time it has to do with the ability to speak the language. During my first year in the US I met zero Poles, only spoke to my parents on the phone twice a month. They live in Poland.
Later I met some Poles but without a whole lot of socializing. The same in Canada. I met a few Poles here because I shop in Polish food stores. Just like I meet Ukrainians, Pakistanis or Irish. I understand the language so I know they are Polish. They rarely know I am :)
I think I went to a party organized by Poles perhaps 3 times in 15 years. Most participants were local people (non-Polish origin). I am a lone Pole where I work (about 150 emloyees).
Strangely, my daughter who was born in the US knows many more Poles in Canada than I do.
