Signing on- I have to do what?

So I have my own authority, insurance, plates, etc, but want to sign on with another carrier. I'm being told that I have to cancel my MC and basically everything in order to legally sign on to another carrier. This doesn't seem right to me. Anyone have experience with this?

 

I want to get back into oilfield work and the contracts are locked down, so the only way is to lease on to somebody that already has the contract.

Looks like I won't be getting back into the oilfield if I have to end my own business.

 

Well pausing is better than ending. Which isn't a big deal, but that also leave IFTA, IRP, etc-

I guess I wasn't expecting the headache the government was wanting to give for simply leasing onto another carrier.
