4 weeks is the max they keep it for. So 4 weeks plus probably 2 weeks of travelling time from Seattle to Moscow is probably a month and a half MAX. It could be shorter than that though. Some people have got their PP back after roughly a week but like I said, they live in BC and you live in Moscow so it will take a bit longer. Congratulations though anyway
I live in Edmonton, AB. I applied for PR through Moscow that's why I was supposed to send it to Moscow or go there to get visa. But they arranged it with Seattle now, so all I need to is to send my passport to Seattle for visa.
sorry for not being clear
