Unlike labor and I-140 - which are sponsor applications i.e. a company has to file them; 485, EAD, and AP are YOUR applications. You don't need company to do it at all. You can do it on your own or find a lawyer who will do it for you.
- USCIS has added 485J that the company needs to fill out. But rest is upto you.
