1.Seeking suggestions on Finland or Sweden study visa for masters.? 2.how much hours part time working in a week.? In Finland and Sweden?
Are you fluent in Swedish and/or Finnish? You will not attend school, and certainly will never work without being fluent in the language. While student visa restricts foreign students to working a maximum of 20 hours a week, the majority of foreign students never find any job at all. To apply for student visa, you must prove you have sufficient funds for all school + living expenses + return transportation to your own country without working at all. no money = no visa. You fail to state your field of study, so no idea whether either country offers internationally-ranked grad schools in your field. And no idea whether employers in your country would accept either a Swedish or a Finnish degree. You could return home with a degree employers in your country don't recognize, don't respect, and you'll have no local references, recommendations, connections to try to find a job when you get home.
If you're getting a study visa, you have to first prove you can afford the full cost of living and studying there. Working on a student visa is very restricted.
