Hello. I am a US citizen. My wife is a citizen of Russia. We have been married for 2 years. At the moment we are waiting for the appointment of an interview for the wife's visa. On August 10, 2023, my wife's sister died. My sister-in-law had a child left without care at the age of 3 years. My sister-in-law was a single mother. In December, a court will be held in the Russian Federation on the adoption of this child by my wife. The child has no other relatives. I, a US citizen, cannot take custody and adopt this child, a citizen of the Russian Federation, since this cannot be done under the law "Dima Yakovlev's Law". Russia is also not part of the Hague Convention. Question: Can I file a petition for this child as my stepdaughter? Or what kind of petition should I file for this child to emigrate to the USA?
