sim, se você tem um visto válido para schengan, está definido.
Romania Foreigners seeking to enter, transit and perform short-stays in Romania, can do that without needing to show national Romanian Visa, if they enjoy a valid Schengen Visa (type C, double or multiple entry). The allowed period of stay must not exceed the period of 90 DAYS within a 6-MONTH period and the visa must be used in the territory of the Schengen area first (For more and updated information please click here!).
