I am most definitely an immigrant. Being in Paris and saying/feeling "I'm only here for a month" has a decidedly different feel for myself and others. For me, I don't have to find a level of sustainable homeyness. For others, I will be spending money here and then leaving.
After I was in Zürich for about 4 months, I visited Berlin, Germany. The vibe there was wonderful and when I saw the RISD originated Andre the giant sprayed all around, I though "This place is far more like the US than Switzerland is."
Almost one year living in Zürich, I visited Vienna, Austria. The Viennesse love of American Football, burgers, and large portions of greasy foods made me think "this place is a lot more like the States than Zürich is."
My time in Italy last spring left me free of any comparissons, so uique was the Tuscany.
Now I am in Paris and while the presence of GAP and Unitarian churches makes me chuckle, it's the reminders of Zürich that give me comfort. The "maccaroons" that look like big ol' Luxemburgerlis (they come in foie gras flavor), the "Mövenpick Switzerland" ice cream in the shops (Ben and Jerry's is more represented here than in Zürich, mind), the plentiful German labels and signs in the organic health food store. They all say home to me.
Home; a word that is difficult to define with each new language I learn.
Meanwhile in my french class a woman describes herself as German-croat and says that she lives in Paris, because she's got a 3 month lease here. I think that she may actually be more american than I.
