I have dual citizenship to two EU nations, and have served briefly in the military of one (Danish Air Force), only basic training. I’d like to serve in the military again, but I don’t feel the militaries of my countries are involved enough in important conflicts. so i’m considering trying to join the US military. I’ve not claim to citizenship, and from what i’ve seen i could only apply for a green card as a 3rd preference immigrant. i know with a green card i can just join the military, but how hard is it to get one as third preference? Or is there any other way into the US military as a foreigner? Any help would be appreciated.
