Travel essentials for Reykjavík

Entry requirements for US citizens

US citizens need a valid passport, but no visa, for stays of up to 90 days in any 180-day period in the Schengen Area.

Your passport should be valid for at least three months after you plan to leave the Schengen Area (six months is recommended). The EU Entry/Exit System has been fully operational since 10 April 2026, so your fingerprints and a photo are taken at your first entry instead of a passport stamp. ETIAS, a travel authorisation costing €20 and valid for three years, is not required yet and has no confirmed start date, so check travel-europe.europa.eu before you fly.
