What you say is very hard to do, unless the embassy makes regular visits to check the situation of each maid. I can

I can only speak of examples I have noted in Saudi..

The maids arrive in country and are usally "signed for" and taken away by their sponsor.

I have witnessed cases of maids being locked in by their sponsor and not having any means of communication to the outside world..

Many a time, they wouldn't know how to , or who to contact.

Its a very difficult situation..
