It is absolutely possible to petition for yourself, especially if you are working in a profession that is traditionally occupied by independent contractors. Some examples of these professions are hair dressers, make-up artists, painters, musicians, to name a few.
What do I need to do before getting started on my petition?
You should find one of your “clients” to act as an Agent for you, to represent all the clients that you will have here in the U.S. This particular client will have to sign a short agent-principal agreement, which our law firm will draft for you, as well as create an itinerary for your time here on the O Visa. He/she will also provide the signature as the “petitioner” on the application.
