Expat Laws to particular oblast/regions

Expatriate Laws unique to federal regions
In Russia there is an active united legislation for foreigners. Each subject has the same laws. But there are differences in the action of the labor patent.

Labour Law
Since 2016 the labor patent for work in the Russian Federation for foreign citizens has a territorial binding, i.e. the territory of action is specified in the patent for work.

Accordingly, a foreign citizen can legally work only in the territory specified in the labour patent.

However there are cities of Federal importance. Thus, a foreign citizen cannot work in Moscow and the Moscow region on the same patent, as the patent is issued either for Moscow or for the region.

However, a foreign citizen can get two patents for work: one patent for work in Moscow, the second patent for work in the Moscow region.

The same law for St. Petersburg and the Leningrad region. For legal work in St. Petersburg, a foreign citizen must have a patent for work in St. Petersburg, for work in the Leningrad region a foreign citizen must have a patent for work in the Leningrad region, or have two patents.
