They can always go back to Russia — the successor state to the USSR.

I know a lot more about Latvia than Estonia. In Latvia, they don’t generally don’t want to leave. Under the Soviets, Russians got the bulk of good jobs and houses and they make up 34% of the population. They don’t want to speak Latvian and making them leave would be ethnic cleansing. Not to mention inviting hostility from Russia. That said, 10,000 - 20,000 a year do voluntarily remigrate to Russia but its a drop in the bucket.
Its a bad situation. The legacy of Stalin continues to hurt people.
