I can recall people moving to the Soviet Union made news headlines and were labeled as defectors. Lee Harvey Oswald made headlines as a defector long before assassinating JFK.
How much has changed? If an American got a job offer would it be a big deal to move to Russia, Ukraine, or the other former Soviet bloc countries ? Is it it any more difficult than moving to Europe or Japan for a job?
An American living in Russia won the Gold for the Russian team in Snowboarding and it got me curious how common it has become for immigrants to live and work in Russia.
