Apply for a visa
If you are from a European Country included in the Schengen Visa you only need your national identity card or your passport. The 15 Schengen countries are: Austria, Belgium, Denmark, Finland, France, Germany, Iceland, Italy, Greece, Luxembourg, The Netherlands, Norway, Portugal, Spain and Sweden. There are some other countries that donít require a visa if the person will stay less than 3 months. Please contact a Portuguese embassy in your country to know if you need a visa.
It's recommended that this process be started as soon as possible. We can provide the invitation letter so long as you have already registered, paid and submitted the final version of your paper. Please note that this letter does not guarantee that you receive a visa.
