Sorry, English isn’t my native language, but do you want to start studying again in EU? In that case, you can apply for an education VISA. I don’t know what is a blue card, but I’d suggest looking at the country you want specifically rather than looking at Europe as a whole. The procedures will be similar between EU countries but in the end, you’re going to be talking to one specific embassy in America. Each countries have different levels of strictness.
