I recently hired a visa service company (Go To Russia) to ensure that I get a full 30-day visa for my upcoming trip to Moscow and St. Petersburg (May 5 to May 15).
I also paid an extra fee to have Go To Russia register my 30-day visa upon my arrival in Moscow. I could have had my hotel do this, but they would have registered my visa only for the days I am staying with them, not for the entire 30 days of my visa.

However, I just found out that I will need to re-register my visa every time I arrive in a new city in Russia and stay for more than 3 days. Since I will be going back and forth between Moscow and St. Petersburg, I have the following concern:

Will there be a conflict between my service company registering my visa for 30 days upon my arrival in Moscow, and my hotels also registering my visa, but only for the days I'm staying with them?* In this case, which registration would count with the Russian government, the one my hotel makes, or the one my visa service company makes?

It is very important to me that my 30-day visa will actually be valid for 30 days. I do not want to have problems leaving the country should there be some kind of delay or travel disruption.


* I will be in Moscow from May 6 to May 10
I will be in St. Petersburg from May 10 to May 14
I will be back to Moscow from May 14 to May 15, then depart to New York.


FYI: Go To Russia does not have a St. Petersburg office, otherwise I would have simply re-registered with them upon my arrival in St. Petersburg.
