I have heard that since some countries are tightening immigration, many foreigners are turning to Russia for better opportunities. Migration processes for persons wishing to obtain citizenship of Russia or the Russian Federation for children can be quite complicated
There are some documents of the process for minors that must be submitted to the consulate and the Ministry of Foreign Affairs: the Diploma of their educational institution and a residence permit in the United States (these marks do not apply to minors with US citizenship). A birth certificate and also a bunch of papers. I recommend you this site to read what else you need.
