Can a lesbian be accepted into a congregation and become a sister?
Yes, most congregations today would accept a woman with this orientation provided that she can live a life of chastity, the same as what is expected of a woman who is heterosexual. Obviously the challenges associated with a same-sex orientation are significant and the candidate would need to face them honestly. Arriving at peaceful ownership of sexual orientation, be it homosexual or heterosexual, is necessary for everyone.
