If you have a criminal conviction in another country that would be a bar to gun ownership if it happened in the U.S., does it "count" as far as the forms and laws in the U.S. go?

For example...that basketball player that got a 9 year or whatever sentence in Russia...is she now barred from owning a gun in the U.S., as a convicted (by a foreign court) felon? Or does she get a pass because it happened overseas?

I'm just curious.
