If this report is to be believed, then you could avoid learning that bloody difficult Polish language, deal with foreign bureaucracy and new-country troubles in English
I have been to Poland many times. I can tell you that you definitely
do have to speak Polish, if you are to have any meaningful long-term interaction with Polish life. Poland is pretty much of a monoculture, and an immigrant could only really be "accepted" by being willing to blend in, have respect for the culture, and adopt their ways and attitudes. They do like America and Americans, though much of this is for perceived economic advantage, which is only to be understandable, I suppose. Strangely enough, they do not really know a whole lot about life or events in the United States, and the impression I have gotten is that this is really of no importance to them, no impact upon their daily lives. The larger cities, most of all Warsaw, tend to be more cosmopolitan than you'd expect. The diet is heavily reliant upon pork, potatoes fixed innumerable ways, sausages, vegetables, breads and pastries of all kinds. Not bad if that's what you like. I grew to develop a great fondness for
kotlet schabowy (pork cutlet prepared like a schnitzel) and
pierogi. The beer is pretty good and stronger than its American equivalent. French fries ---
frytki --- are if anything more common than they are in the United States. Being a competent ballroom dancer (I'm not) is a great social lubricant. It is not a bad place, but it can get pretty monotonous after a while. Traditional Catholicism is not unknown but it is still kind of a fringe movement --- this is truly the land of John Paul II. For those among us who are fond of the Second Amendment, gun ownership is virtually unknown except for hunting purposes and
very strict requirements for personal protection --- handguns basically do not exist, and you would pretty much have to go to a gun club and rent one to use while you are there.
