I'm a photography artist and have recently become also a tech start-up entrepreneur. We're now looking into moving into the US within the next year or so and I'm looking into the visa options. What would be the visa to apply as an start-up entrepeneur? I have also considered applying for the O-1 visa as an artist. Can I work as an artist if I have received my visa on the basis of the start-up and vice versa can I work in a tech start-up with an artist visa O-1? I am from the EU.
