* Russian: The primary language of Russia, and thus the most common language spoken by Russian immigrants.
* Ukrainian: A distinct language spoken in Ukraine, which is also home to a large Russian-speaking population.
* Belarusian: Another Slavic language, spoken in Belarus, which also has significant Russian influence.
* Yiddish: A Germanic language spoken by Jewish communities throughout Eastern Europe, including Russia.
* Other languages: Depending on the specific region of Russia and the immigrant's background, they may have spoken other languages like Polish, Lithuanian, Latvian, or various Turkic languages.
It's important to remember that language is a complex and dynamic aspect of culture and identity. While Russian immigrants may primarily identify with the Russian language, they may also speak other languages depending on their background, upbringing, and exposure to other cultures.
