Hello, I will come in Chicago coming fall for 3 months. I am contemplating immigration and want to experience the city before going further. I will trade from my broker's office in the CBOT on a daily basis, along with meeting people, immigration lawyers and so on. Which visa do you think I need ? I won't look for a US based job but I will trade on a daily basis in their trading room and this is my job in France, I am registered as an individual. I will trade the Chicago exchanges with my account in the US. I called the US embassy and made it clear I would trade on a daily basis on my individual account, the guy told me a B2 business visa is enough. As a french, I have a visa waiver when it is less than 3 months. I just half trust what the guy told me. Has someone tried to trade for short period in the US as a professional paying taxes in an other country? I am just super scared of being busted at the customs :" You are a professional. You can't work in the US. Good bye, Sir". What do you think? Thanks a lot.
