What kind of artist? Graphic artist? Painter? "Performance artist"?
If you're looking for employment as an artist, you're in pretty much the same boat, whether you're looking for work in the US or in France. If you're looking to make your name and fame as an artist, it comes down to the old joke about "How do I get to Carnegie Hall - Practice, man, practice."
Finding a job in France is, at the moment, a real tough way to go. Employment, particularly among young people, is at a high point. To find an employer who is able to sponsor you, you pretty much have to have something "unique" to your skills - which is where the "practice, man, practice" part comes in. If you can make a name for yourself in your chosen art form, it would make finding employment (in France or elsewhere) considerably more likely.
It's not impossible - but it may take time and patience.
