That really depends on what sacraments she has received and how RCIA is handled in the parish she attends.
If she had not been baptized before then she would receive all three sacraments of initiation (baptism, confirmation, first Eucharist) at the Easter vigil.
If she has already been baptized in a non-Catholic community then she would make a profession of faith, be confirmed and receive first Eucharist. This might or might not happen on the Easter vigil. Our parish delays receiving candidates for full communion until the first Sunday after Easter where other parishes might receive them during Easter or even at other times of the year.
Finally, if she was already baptized in the Catholic church as an infant (i.e. before 7th birthday) then she is already Catholic and the parish might push her through RCIA or an adult sacramental prep class depending on her level of catechesis in the Catholic faith. When she might receive the sacraments is completely up to how the parish does things.
Like I say, it really depends on if she was baptized already and how the parish does adult formation.
