99% of FL will be sent back immediately. 1% will stay back willingly or unwillingly.
Willingly case, is FL themself go lodge complain against boss in return for white card so they can carry on working here for a indefinite time.
Unwilling case, is police has some evidence, and require FL to assist in investigation. But they still work as FL to supplement their income.
Its a win win situation to get a white card. To the extend, many are exploiting this loophole
