When you apply for a Finland Tourist Visa you need to put together a list of required documents:

• Valid passport. It’s important that you hold a valid passport when you apply for a Finland tourist visa. Your passport should be valid even three months after you return from your visit and it should have been issued during the last decade.
• Finland Tourist Visa Application Form. You have to fill in the visa application form so that you can attach it to your documents. Please make sure that you fill it in with the correct and updated information.
• Identity Picture. A recent identity picture is also required. You should make sure that you are following the Schengen visa photo rules when you take your picture.
• Travel Insurance. In order to qualify for a Schengen visa, you need to provide travel insurance. The insurance needs to be up to the amount of €30,000 and cover any kind of medical emergencies during your travel.
• Travel Itinerary. Some embassies may ask for a detailed travel itinerary where you write your departure and return dates, your flight number, and your visit plans. They usually ask for this to make sure that you won’t be overstaying after your visa is expired. You don’t have to actually purchase a ticket for this; you can simply reserve the flight tickets.
• Proof of accommodation in Finland. You need to provide evidence that you have secured accommodation for the duration of your stay in Finland. You can either attach proof of hotel bookings or rental agreements.
• Copies of Previous Schengen Visas. If you were issued any type of Schengen visa before you apply for a Finland tourist visa then you need to attach the copies of that visa to your application.
• Copies of Previous Passports.
• Copy of Passport Bio Page. Finland now requires that all applicants attach a copy of their passport’s bio page to the application, so make sure you add that as well.
• Financial Means. You must also provide evidence that you can finance your visit to Finland.
• Invitation Letter. If you were invited by a family member or friend then you must also attach an invitation letter to your application. This letter should contain all the details of your inviter and their residence status.
• Employment Status Document. Depending on your current status you may be asked to provide:
  • Work contract.
  • Pension statement (if retired).
  • Student records (if a student).
• Cover Letter. You also need to write a cover letter where you state the reason why you want to visit Finland, where you plan to go, and when you will return.
• Civil Status Documents. You may also be asked to provide copies of your birth certificate, marriage license, divorce papers, or adoption papers. It all depends on your personal situation and the embassy.
• Residence Certificate. You need to provide a document proving that you are living legally in your current country of residence.

Keep in mind that when it comes to requirements the embassies can ask for any other documents depending on various reasons. You may also be asked to legalize some documents, please make sure you check in with a local Finnish mission.
