Portugal Guide
Entry requirements
EU citizens need only a valid passport or identity card to enter Portugal, and can stay indefinitely. Citizens of Canada, the US, Australia and New Zealand do not need a visa for stays of up to ninety days. Most other nationals will have to apply for a visa from a Portuguese embassy or consulate – there's a full list at 
www.embassiesabroad.com/embassies-of/Portugal . Entry conditions can change, however, so check the situation before leaving home on www.eurovisa.info .
If necessary, an extension to your stay can be arranged once you're in the country. Extensions are issued by the nearest District Police headquarters or the Foreigner's Registration Service – Serviço de Estrangeiros e Fronteiras ( www.sef.pt ) – which has branch offices in most major tourist centres. You should apply at least a week before your time runs out and be prepared to prove that you can support yourself without working (for example by keeping your bank exchange forms every time you change money). Extended stay visas are also available through Portuguese consulates.
