Good choice of topic.
It will be interesting to hear what our American cousins think.
Lopata (1976) argues that Poles differed from most ethnics in America, in several ways. First, they did not plan to remain permanently and become "Americanized." Instead, they came temporarily, to earn money, invest, and wait for the right opportunity to return. Their intention was to ensure for themselves a desirable social status in the old world. However, many of the temporary migrants had decided to become permanent Americans.
I think this was the case with many other immigrants, longing for a chance to return home.
In a somewhat related theme Polish American Journal.
