Poles coming on a tourist visa to USA and don't return like they are suppose to, when their visa expires and staying here illegally, also ruining chances for other honest Poles for getting a visa.
You're giving Poles too much credit. they are a drop in the bucket in the US.
American jobs went to mostly to China, India, Mexico and such. And if that wasn't enough millions of Mexicans are pouring though the so called US border. They aren;t even sure how many. 10 million? 20?
That has little to do with Poles and everything to do with the greed of large corporation. America is on a downhill slope and so people will try to pry some of the last remaining dollars and then there's gonna be a big bang, and even less reason to go to the US than there is now. And that also has nothing to do with Poles.
