Non-EU/EEA students need a student residence permit. After you receive your official letter of acceptance, you can begin the student residence permit application online at Enterfinland.fi. Remember that you must personally visit a Finnish embassy or consulate as part of this process. Start your residence permit process as soon as possible, so that you can receive your permit in good time before your studies begin!
After your graduation, you may apply for an extension of your residence permit to look for work or start a business.
You can find detailed information on the residence permit requirements and procedures on the Finnish Immigration Service (Migri) website.
