I'm currently in the US on a B1/B2 visa, with B2 status, so I know that I can't work. Now, a company is offering me a job position and they will sponsor my H1B but first they want me to work for them during a trial period (2 months) before the contract and H1B process. I can stay until May this year, so the staying here for 2 months is not a problem but I'm not supposed to work, they mentioned to work as a consultant. Is there a legal way to do this?
