But you can not go to hajj until its time for hajj, so what you meant was umrah. Hajj is only around a certain time, for a set amount of days. Umrah you can perform at any time.
As stated, the sister has been banned upon request. InshaAllah she will return, and even if she doesn't, may Allah protect her and keep her on the right path always. Ameen.
As for the Hajj thing, Umrah is also referred to as Hajj al Asghar (The minor Hajj), so perhaps that's why you said that. And Hajj is two months after Ramadan, in the month of Dhul Hajj.
Anyways, the main purpose of this topic has been served (regarding the sister), and we're derailing...lol.
