Nikon DSLR camera warranty?

I have Nikon D3100 camera and it's broke. Now I need to fix it, but i have no warranty and camera is bought from some America's store ( I live in Europe). If I'll take my camera with me in America would it:
1) be fixed by Nikon?
2) be fixed in a month?

or it's impossible that Nikon would fix it if i have no warranty?

I would call Nikon first and ask. They have excellent customer service and often make repairs out of warranty.

Unfortunately, a great deal of Nikon sales here in the USA are by unscrupulous retailers offering cameras intended for other markets. These are called "gray market sales," and do not include any warranty at all. They offer the customer a great price, but if the camera ever stops working it can be difficult or expensive to get it fixed.

You will have to call Nikon and ask where to send it for an estimate for whatever repair it needs.

"Broke" covers a lot of ground. Did you drop it? Did it get wet?

When in the US, you can call 800. NIKON-UX
