Currently I live in Lithuania, and I have no relatives in the US. Im 19, so I dont have a job either. But I want to immigrate to the US and get the citizenship. I know there is a way to do it through the military, but im not sure how should I do it "step by step"
Your first step is to figure out a way to get to the US that is either temporary or permanent, meaning you must be living here in the US. Then, you can apply for the military. Speak with an attorney.
