Affiliate Marketing Secrets

Hello! I’ve been thinking about moving to Sweden, and have a couple of questions about the lifestyle.
Currently I’m living in the US, enrolled in high school, and wanting to learn Swedish. Here are my questions:
1) Does Sweden have a credit score system?
2) Are marketing/advertising/design jobs hard to get?
(I’m still in high school, but wish to pursue a major in these areas)
3) Also, do I need a couple of years’ experience before I can get that job (in question 2)? What are some good things to add on a resume?
4) Is it a burden/annoyance for businesses to get a work permit for someone they just hired that isn’t from Sweden? (For those of you who have moved… is it hard moving there?)
5) Will businesses be inclined to hire me if I know Swedish? (Also, will my ‘perspective’ help businesses who want to reach out to the US?)
6) Are there some international banks? (That are affiliated/shared with US banks)
Thank you very much for your answers and time! Sorry if my questions are a little awkward. 🙂
