Because your wife is a Russian citizen and she permanently lives in Russia, and your marriage was registered in Russia, therefore, the court in Russia cannot decline to review your case, and this case can be reviewed in Russian court. In order to start divorce proceedings in Russian court you do not have to go to Russia. You can retain a lawyer in Russia and issue a power of attorney in the lawyer's name. If this power of attorney is going to be certified by US notary public, you have to do apostille for this power of attorney at secretary of you state to make this document valid outside the USA.
