I obtained my visas in May 2015 - On the application I listed the dates of my first stay ( Three weeks in St Petersburg , from the end of August to late September ) At the end of my visit , we departed for Helsinki . I did not list dates for a three year visa , but only applied for it ( Dates on Visa as follows - issue date 20.05.15 - dates of validity 31.08.15 - 30.08.18 ) You only need to indicate for stays on your first entrance , as well as a formal invitation , which you can easily obtain from your hotel , and the information about your valid health insurance at the time of application . If there is any question about the validity and/or applicabilty thereof , I would buy appropriate travel insurance ( I use Travelguard ) . both the invitation and health insurance will need to be entered on your original online application , which you will print out for submission at ILS . I am sending you a Private message as well .
