A full list of accredited agencies currently working in Moscow is on the US Embassy Moscow website. However it does not have dates of when the agencies expire.

The Russian website has the dates, but it is not always current. For example the agency that I used is not on this list, but was reaccredited a couple of months ago. It also shows agencies whose accreditations recently expired.

Here is the same site in Russian. You can use a website to translate for you.

Finally you can look at the JCICS website. Only members of JCICS are listed, but you can get dates here too. Members need to fax proof that they are accredited to be on this list. They also redirect you to the US Moscow Embassy's website for a complete listing.

I hope this doesn't violate TOS. If it does please PM and I will forward these websites.
