After reading all the posts I have to admit that I misunderstood the problem.
So your maid is a foreign live-in domestic worker and she is working illegally for you and for others.
Is she "sponsored" by someone who gives got her a work permit and gives her a place to stay probably for a no mean consideration - say 3 big ones?
Then she's got to take in a lot of p/t jobs to earn enough to pay for her the levy ($345) and in order to pocket $350 she's got to earn maybe $1,000 because she's got to reimburse her "sponsor" for the levy; and she's got to pay for transportation and food.
And if time is money, she just might commute in style, by taxi. If she gets paid $12 an hour, it woud not make much sense to wait for a bus and walk part way. So the $1,000 she's got to split with the cabby too.
But I have heard too many stories about fdw not honouring their debts. I mentioned that your chances of getting you money is less than 50-50, now I would estimate it at 20-80.
If I were you, I would not expect to get it back.
