Yes, there are such examples: they include a Russian man who was issued a Uruguayan passport and a Belarusian citizen who received a Uruguayan passport in 2021. This confirms that this route is not merely theoretical for people from Russian-speaking countries.
But isolated stories cannot be taken as a promise of the same outcome for every applicant. Important factors include years of residence, legalization, a cédula, documents proving income and ties to the country, registration formalities after a positive decision, and only then passport processing.
If the purpose of relocating is specifically to obtain a passport, it is worth considering not only the existence of successful cases, but the entire path leading to them. Uruguay is better viewed as a country for real life and integration, with a passport as a possible culmination of that path.
