SDEWES2016 Conference will be held in Lisbon, Portugal. Portugal is a part of the Schengen area, for more information on the visa policy of the Schengen Area see here.

The Portuguese authorities may issue two types of visa. The visa type is indicated on the visa sticker in a special section and marked with the letters A or C. For coming to the conference, you will need a type C multientry visa. A uniform visa (type C) entitles its holder to free movement throughout the entire territory of EU Member States.

In principle, a visa application should be lodged at least 15 calendar days before the intended visit (as this is the normal processing time) and cannot be lodged earlier than three months before the start of the intended visit.

Who does not need a visa?
A short-stay visa (stay in the Schengen area of up to 90 days) is not required by:

  1. Nationals of EU Member States or Contracting Parties to the Convention implementing the Schengen Agreement of 14 June 1985;
  2. Nationals of third countries listed in Annex II to Council Regulation (EC) No. 539/2011 of 15 March 2001 (Official Journal of the European Union L 81 of 21 March 2001, pp. 1–7) listing the third countries whose nationals must be in possession of visas when crossing the external borders and those whose nationals are exempt from that requirement (including amendments);
  3. Holders of diplomatic, service or special passports of countries with which the Republic of Portugal has signed an agreement on the abolition of visa requirements;
  4. Holders of valid Schengen visas (type C) of other Contracting Parties to the Convention implementing the Schengen Agreement of 14 June 1985;
  5. Holders of valid residence permits issued by Schengen States, provided that these permits are included in the list of residence permits entitling their holders to travel without a visa;

If you are not sure whether you need a visa for coming to Portugal, please contact your nearest Portuguese consulate/embassy.

Where to apply?
Information on the diplomatic missions and consular posts of the Republic of Portugal where you can submit your visa application is available here. Following its entry into the Schengen area, the Republic of Portugal is also represented in the visa procedure by some other Schengen States. Thus, at locations where Portugal does not have a diplomatic mission or consular post authorised for conducting visa procedures, you may apply at the representations of Schengen States.

How to apply?
On Portuguese visa portal you will find online visa applications, a detailed description of the circumstances under which a visa is required, and a description of different visa types. For additional information on visas, please contact them via e-mail or telephone (+351) 213 963 086. Application Form for Short-stay (Schengen) visa are available here.

The Conference will issue a certified Letter of Guarantee, necessary to apply for a visa, only to registered participants with accepted papers, due to significant cost of such a Letter to the Conference. The participants may only request certified Letter of Guarantee as part of the registration procedure. The Participants are advised to start the visa procedure latest by beginning of June.
