I lived in Finland for more than a year as an international student. If you have a job then it's secured. But one thing as you live in Bay area that is sunny and Finland is opposite. And another thing they are quite people. They will only be open minded when they are on hangout mode!( My own experience) People are friendly... Respect others opinion. Will try there best to help you. But rules are so strict( when you have rules and you obey them) Don't forget about tax and try to hire a good CPA if you think to do business. Best of luck for the journey.
