i'm not qualified with any skills, i'm straight out of school, i'm 18, and don't speak a word of polish, but i want to experience how hard it is for Foreigners to come to britain, so i've switched it around.
You're not comparing like with like - many of the Poles who came to the UK (and stayed) are well educated and/or skilled, and many of them came over with basic English. We've got high unemployment here so you'll find it pretty impossible to get a job if you can't even speak the language. The advice to get a TOEFL qualification is good. I think that unless you have some skills to offer here, you're not going to get far.
