OSWALD'S travel from Minsk to Moscow and return in July 1961 would normally have required prior authorization. Bearers of a Soviet "passport for foreigners" (vid na zhitelstov v. SSSR dlya innostrantsa) are required to obtain travel authorization from the Visa and Registration Department (OVIR) (or Passport Registration Department (PRO) in smaller towns) if they desire to leave the city (or oblast) where they are domiciled. This same requirement is believed to apply to persons, such as OSWALD, holding Soviet "stateless passports" (vid na zhitel-stvo v. SSSR dlya lits bez grazhdanstva).
