I want to stay in Russia, what should I do? I can speak Russian. Introduce in detail

You must have a legal visa to go abroad.

Either student status. Find a school in Russia to send you an invitation letter. After you go there, find a school that doesn't require classes. If you pay one year's tuition, you will be given a one-year visa.

Either a work visa. Russian companies have quotas for inviting foreigners to work, and many intermediaries are selling these quotas. 1 year to 3 years. Thousands of dollars.

If you want to stay in Russia permanently, you need a green card or Russian citizenship.

One way I know is to sign a long-term work contract with a Russian company after graduating from higher education in Russia. You can apply for Russian citizenship.
