There are 4 conditional waves of Russian immigration to the United States.
The first was connected with the Russian development of America in the 18th-19th centuries and was represented by small Russian researchers who founded settlements along the Pacific coast.
The second took place at the turn of the 19th and 20th centuries and was represented by Jews from the Russian Empire.
