<p>I don't live in the USA, but I want to study in California. As far as I know, people who turned 18 can live alone. I turned 18, but I'm not a legal adult because I didn't turned 21 so I can't live alone in other country without my parents, can I?</p>
<p>Yes people can live alone in America if they are only 18.</p>
<p>I believe you can just get an education visa and stay for college. I don’t know the protocol for transitioning to permanent resident though.</p>
<p>Yes, you can live on your own if you are here on a student visa.</p>
<p>Would you want to live alone ? Any relatives here ?</p>
