Importing problem

i have a problem, when i try to import a model with rig into unity from MAYA, if i import in OBJ format, it will come without any rig, but with the model, also if i import in FBX format, it will come as a “prefab” of an avatar with the rig bones, but no model…

what can i do to solve this???
first time happens… and i have imported a lot of things and things with rigs included, but this is the first time with this trouble…
