foreigners 992.for.01 Louis J. Sheehan, Esquire

Foreigners required special documents and had to be registered wherever they lived. There were certain areas they were not allowed to enter. For example, if one had a visa and permission to live in Moscow, one could not stray farther than 20 km from the center of the city without permission from the authorities. A special arm of the NKVD was assigned the task of observing foreigners in Russia.
