Hello, I think since you want to work in research and not in patient care, it would not make sense to do a 6 year gruelling MD program at Jagiellon.
I think you should look into programs within the UK, and Ireland for a 3 year undergraduate degree because you will get EU tuition and support to pay your fees from the EU government, and your parents. (I believe since Britain is leaving the EU the 2019/2020 academic year is the last year of support offered for EU citizens studying in the UK. This means that 2022 is last year EU will cover students). Take advantage of this while you can.
Additionally, programs in the UK and Ireland are more respected back in North America. Afterwards, you can decide to either do a research degree in the EU or North America. PhD programs in science are usually funded in the US.
So, If I were you I would do this:
3 year degree in England, Scotland, Wales, or Ireland where I could get EU tuition until 2022 plus have the support of my parents if I start 2019/2020 academic year. Then a PhD in the US which is fully funded. Masters degree programs aren't needed in the US to get into a PhD program. As well, masters programs are usually expensive and unfunded, many students take out loans to cover the cost of the masters program.
