USA vs. UK vs. Canada vs. Sweden for Bio fields?

I'm finishing my high school next year, so now I have to choose the uni and country I wanna study in, and its quite tough for me to choose. I have my options (USA, UK, Canada and Sweden), I'm majoring in bio related fields, and after graduation I'm planning to stay and get a job, and I know that it's pretty hard to get a job without citizenship and not knowing the language(Swedish) . So, if anyone has been through it, could you please share your tips, and how you chose uni, and how to adapt
