KO______ Why do you think the process will be impossible?
I spoke to one Russian friend, Yulia, and plan to discuss it with more. But the process seems manageable. There is a notary, an MFC, and an MTS store within a short walk of my Moscow apartment. So, on my first day in Moscow, I could visit all three to complete the process. Yulia said the MFCs are usually fast and perhaps I will be able to do much of this at the MTS store. I can email the notary before I arrive to arrange the translation.
But I will know more once my expat friends who are already in Russia complete the process.
