Invitation for Visa Application

Passport and Visa

To visit Portugal you must have a valid passport or, in the case of European Union Member States, a national identity card. A visa is required for the citizens of countries that do not have visa-exempt agreements with Portugal.

Please contact your local Portuguese Consulate to learn more about visa acquisition.

For many participants, letters of invitation help smooth the visa process. We wish to support international attendees in their efforts to secure the needed travel documentation. However, in order to receive a letter of invitation, MEMC-GREAT must be assured that you intend to attend the meeting if your travel request is granted. Individuals that require an official letter of invitation in order to obtain a visa and authorization to attend the meeting must:

  1. Register for the meeting
  2. Request a Visa Letter of Invitation

We require that you provide your full name, address, and email for us to process the electronic official letter of invitation. The letter of invitation does not financially obligate the MEMC-GREAT Scientific Meeting organizers in any way. All expenses incurred in relation to the meeting are the sole responsibility of the attendee. Please note that we cannot guarantee that you will receive a visa. The decision to grant visas is at the sole discretion of the embassy/consulate. The meeting organizers cannot change the decision of the governmental agency should your application be denied.  Due to the costs involved, we cannot send letters of invitation via express mail services.

Advance travel planning and early visa application are important. It is recommended that you apply early for your visa.
