Fostering a child doesn't make the foster parent(s) related to the foster child; it just gives said child a (temporary) stable environment in which to live.

As far as the SQ/Sarah Fisher being a foster parent, I don't think Emma was actively being fostered any longer by the time she turned 11 given that she was in a group home by that age and seemed to have no hope of ever finding a home. She would've still been listed as a foster child, but if nobody wanted to take her because of her age, she'd be stuck living in group homes until she 'aged out' of the system at age 16.

It's for that reason that I think the SQ/Sarah Fisher was a Social Worker for Emma rather than a foster parent, and that something was definitely done to her (Emma's) memories in order to make her forget who Ms. Fisher was.
