That's a great idea, however English is the thing now.
Precisely because the overwhelming majority of these students have their sights set on the UK. Extremely few could be bothered to learn Polish.
Pay attention to the type of students who post here. By far the majority are economic refugees interested in Poland solely as an entry point to the EU and will abscond at the first opportunity. They have paid "consultants" or "agents" to help them get into sham or real schools. Sham schools like the one in Józefów.
A smaller group are those who don't have the means or wherewithal to study in richer countries. Some of these have enough resources to study in Poland without working. The bulk don't, however, and are counting on finding work paid well enough to fund their studies and stay. They have also usually paid "recruiters" who have told them that 1) a diploma from an English-language course in Poland is worth something on the job market in richer countries, which is rarely the case; and 2) part-time work is easy to find. By far the bulk of these will be forced to abandon their studies due to lack of funds or because they figure out that their studies are a waste of time and money.
Exceedingly few are graduate or professional students with stipends or fellowships.
Polish state universities are in on the scam. They offer English-language courses as a way to earn discretionary cash for the university. They have little incentive to provide a quality education. They also run a website that makes it sound as if it is easy for foreign students to find work in Poland. You have to read pretty deep to find the part "unless you are from a third-world country".
These English-language courses are a joke as far as the quality of education and the value of the diploma are concerned, with very few exceptions. Most programs accept anything that breaths. Even the English-language engineering programs are far, far inferior to their counterparts in richer countries, and the degrees are far less saleable. Poland just doesn't have sufficient R&D funding to support quality engineering programs. The same with the English-language medical programs, as potential employers know the drill already.
My advice to serious students stands. Study in a rich country if you can. Study at a good university in your own country if you can't. If you are unable to do either, then studying in Poland is likely to be a waste of time and money, as you will most likely drop out, and even if you stick it through, the degree is likely not to be worth the investment. Unless you are and enterprising top student and take a few years to learn Polish before you arrive.
And you have by no means disproved my statement that by far the majority of third-world students will never earn a single penny during their stay in Poland. "More and more" jobs is a hollow promise when the starting point and ending point are both "practically none".
