Yes, I'm afraid that "single status" is very common! Almost all the lower paid workers from the sub-continent here are not allowed by their contract and their salaries to bring their families. Some of the oil workers who work on the rigs and then have large blocks of compensatory time off are not on family status. However, a job for an educated professional usually is given family status and is provided housing, medical, transportation and education fees for (3) children as well as paid vacation and tickets. Do not come without all the above!
