If California has suspended your driver's license for unpaid child support, the suspension would cover all license classifications. Perhaps your best hope would be to address the issue back in Boston to see if you can negotiate some type of resolution as to the payment of the back child support.
There is an interstate agreement to honor actions taken by other states against your license. You'll have to get the suspension lifted in Mass. To get the suspension lifted in CA.
It is not entirely clear what state you are actually licensed to drive in. With that said, in order to have the suspension lifted, you will have to address the underlying reason for the suspension. I think your best bet would be to contact an attorney who practices in Mass. Avvo should be a good resource for you to find a couple of attorneys for you to call, and most should offer a free consultation. Good luck.
