Citizens of the European Union, Switzerland, Japan, Canada and the United States of America can stay in Romania for up to 90 days without a visa. Turkish citizens can stay for up to 60 days without a visa while citizens of ex-Communist Eastern European countries can stay for up to 30 days without a visa.

Changes in visa requirements will be subject to change once Romania joins the European Union. Most likely they'll be aligned with the entry requirements of the rest of EU's member states.
