List of Embassies/ Visa

Customs

Theoretically there is no restriction on how much you can bring into Austria from other EU states. However, to ensure these goods remain for personal use, guideline limits are 800 cigarettes (25 cigarettes if entering by car or ship), 200 cigars, lkg tobacco,  10L of spirits, 90L of wine, 110L of beer and 20L of other alcoholic beverages. The same quantity can be taken out of Austria, as long as you are travelling to another EU country. For duty-free purchases made outside the EU, you may bring 200 cigarettes or 50 cigars or 250g tobacco, plus 2L of wine and 1L of spirits into Austria. Items such as weapons, drugs (both legal and illegal), meat, animal products and certain plant material are subject to stricter customs control.

Visas

Visas for stays of up to three months are not required for citizens of the EU, the EEA (European Economic Area), much of Eastern Europe, Israel, USA, Canada, the majority of Central and South American nations, Japan, Korea, Malaysia, Singapore, Australia or New Zealand. All other nationalities require a visa. The Ministry of Foreign Affairs website, www.bmaa.gv.at, has a list of Austrian embassies where you can apply.
If you wish to stay longer you should simply leave the country and re-enter. EU nationals can stay indefinitely, but are required by law to register with the local magistrate's office (Magistratisches Bezirksamt) if the stay exceeds 60 days.

Austria is part of the Schengen Agreement which includes all EU states (minus Britain and Ireland) and Switzerland. In practical terms this means a visa issued by one Schengen country is good for all the other member countries and a passport is not required to move from one to the other.
