How to adopt from Russia and immigrate the child to USA right away being permanent resident and Russian citizen?

The adoption law for immigration purposes is complicated. You can start your research on www.adoption.state.us. Keep in mind that (1) Russia is not allowing adoption by US citizens or LPRs so you will have to adopt as Russian citizen; (2) it is never right the way; (3) Russia is a Hague convention country so the process you will have to follow is going to be for a Convention country. https://www.hcch.net/en/states/hcch-members You can also read here: https://travel.state.gov/content/travel/en/Intercountry-Adoption/Adoption-Process/understanding-the-hague-convention.html However, there is also a posibility that since you are a Russian citizen and the adoption is not intercountry adoption really, the fomaly processed adoption in Russia could be sufficient to establish qualifying relationship for family based immigration under F2A category.
