How do we know which accommodation we will receive?

Adeel,

If you do a bit of reading of recent messages, you will quickly see that what your HR advisor told you is true (and the only thing she can tell you). You will find out where Aramco will put you on arrival a week or two before your flight.

Housing here is tight - incredibly tight. Most (but not all) new arrivals are placed in one of the local compounds on arrival. If you are coming on US dollar payroll, you will be placed on a list to be moved to Dhahran when housing becomes available (because Americans on the local compounds cost Aramco a lot for covering tax liabilities for Americans living outside Aramco-owned compounds). Right now, I believe that most new arrivals are going to Radium, but know of other arrivals going to Rakah and to Dhahran Towers.
