Definitely if her company cancels her visa she has to wait for the 2 years ban in order to work again. She can come anytime on family visit visa but she can't work because of the 2 years ban. If only her husband could apply her a family resident visa then there would be no problem. But I guess her husband salary is below 10k. Besides it's not easy nowadays to get a family visa. She got no choice but to return to where she really belongs. Anyway she can come anytime on family visit visa.
