Finland is a member of the Schengen Agreement, which means that visitors planning to stay in the country for fewer than 90 days do not need to apply for a visa or entry permit. However, all extended stays and some individuals seeking employment or planning to study in Finland will be required to obtain an entry permit or residence permit depending upon the length of stay. If one plan to take up employment in Finland, even if it is just temporary or short-term, make sure to obtain in advance all the necessary work authorization papers and, if not self-employed, a letter from the employer. Without proper papers, neither a visa nor a residence permit will be issued.

This is just a sample of what you'll find in the complete Finland guide.
