I haven't found an apartment yet. We are still looking. Thanks for the info. So she would have to be considered as a roommate, in order for her to live with me?

Not necessarily. Just make sure you are allowed to live in the apt in addition to you.

So I can have just my name on the lease, and still have her live with me? Most apartments are ok with that?

Yes as to your first question. I don't know on the second.
