I want to start a C corp while on h1b. I understand that I cannot work for te business but I can own it. However, to apply for EIN (tax number for companies, equivalent to SSN for people) I need to enter my SSN on the form and by doing that I will be considered a ''responsible party". Is this legal? Has anyone obtained a EIN while on h1b? I feel weird about putting my SSN on the form, do I have anything to wory about?
