Yes, i'm EY crew
There are rules about living in DXB whilst working for a company based in AUH & i'm not 100% sure on them. I think it boils down to if you are married & your partner works in DXB then you can too. If not then i think you are expected to live in AUH. I've met crew who live there & they are all married.
Best to speak to someone in the office about this if you can though as i live in one of the company apartments & have never enquired about a move anywhere. Also search this site as i remember someone recently posting information about this, possibly in the wannabes section.
Sorry i couldn't be of more help.
