I dont know anything about WY, sorry.  But if she lives in CA and is running the LLC business in CA she needs to register as a foreign LLC with the CA Secretary of State...not sure why people form LLCs outside the state, that may have worked a decade or 2 ago, but CA wont let you get away with it anymore.
