I believe that this would depend on your employer. It's pretty cheap if they refused to give you the accommodation simply because your family wasn't there yet. That said, I wouldn't put it past some companies in the Gulf to try this. My new employer has already told me it would be easier if my spouse comes after me by a few months as it will take a couple months to sort out my sponsorship. Once that's done, I sponsor my spouse. I still receive the allowance given to married candidates which is marginally higher than the one given to single candidates.
