The people who have responded to your post have already told you what you need to do to work as a director for film or TV.
You need to gain experience; no one is going to hire you without experience and the experience has to be, not just good, but great if you hope to make it in the US.
There are thousands of US high school students now producing their own little films with their phone cameras. My children played tennis with a student who went to NYU for film school. He made a number of little films around the neighborhood and on his high school campus. He had to arrange his own actors, his own equipment, permissions to film “actors” and use of locations. When he couldn’t get help from his family and friends he had to do everything on his own. He’s been doing this type of work for more than 10 years.
Is he a film Director in the US?
I think so.
Is he getting paid?
Some, but not much. His parents support him.
Is he well-known? No
I think you have a very narrow and naive idea of what it takes to direct. You don’t just go to film school and expect that they will teach you how to be a Director.
You learn it on your own.
No one pays you to do this Unless you’re a very exceptional Director and have experience with multi million dollar films that you’ve directed.
A number of film students have a really rough time getting into the industry. They work on basic jobs, sometimes for free. They don’t get paid a whole lot and they spend years trying to direct any films. There’s no way you’re going to get a US work visa if you don’t earn any money.
