Visa in My Old Passport
I have one more year of validity for my Russian visa (I'm a US citizen) and am planning on going this July. The catch is, it's in my old passport that is now expired (along with a few other visas as well). The three whole punch they do through the passport when I got my new one cut out some of the numbers in the visa at the very bottom.
Is the visa still valid/can I travel to Russia this summer if I simply bring both passports? Or do I need to get a new visa in my new passport, even though the old visa is still within its expiration date?
