don't know your field. i do know some guys opened their own home business to hold their legal status. for example, if your work is software db etc, you can startup a consultant firm, it's easy to get some part-time job related to your previous field, if you are CPA, you can statup a financial firm. some guys directly open a on-line shopping website to sell T-shirt etc. Or you can tell the interview IO, you are planning to startup your family business related to your field when you get renewed EAD for better talk care your baby. It's their fault to delay your business.
