You must remember, though, that you will be expected to pay for your studies. In Poland, medical studies for foreign students are conducted in English and I believe it’s possible in the three countries you have mentioned. If not, you would be expected to study the language for at least a year before being enrolled in program of your choice.

And don’t forget that obtaining a foreign medical degree does not allow you to practice medicine in your own country.

You would still have to take extra exams, do your internship, before obtaining your licence.

But a lot of foreign doctors do just that, so that is not such an impossible thing.
