Most likely, after your child was born you registered her as a Russian citizen. This consent has let your ex-wife to take the child from U.S. to Russia.

Where and when your divorce was documented?

Was during the process of divorce the way of communication determined (custody? visitation?). If yes, please send me court decision about it.

Do you see the child now and if yes how often?

How old is your daughter?

Please send me all documents pertaining to your situation (Marriage, Divorce, Birth Certificates, Court Decision, agreements, etc).

Now to obtain the custody for your child for you is practically impossible.

To do so in order to proceed you would need the proves of bad nutrition of your child the existence of physiological or physical harassment from your ex-wife toward your child.

Every fact of abuse should be documented. If you believe that your ex-wife is mentally incompetent than such facts should be medically documented as well.

Only under these conditions you may have a chance.

For time being you can participate it the child’s life.

By default, both parents have equal rights to participate in the child life. You can request the court of law to schedule the time and frequency of visitation. If your ex-wife fails to follow this court order, you may have some grounds for obtaining the custody of your child.

This way is so long and expensive. If you decide to proceed I will be glad to help you.

I am waiting for above mention documents to be sent.
