Sponsor has a legal responsibility if maid get caught

As sponsor you should allow maid time off

As sponsor you should advise maid that she is free with her personal life as long as she does not get in trouble

As sponsor you should build a trust relationship with your maid to share with you her problems before they become serious problems

Rules at home should be made clear and concequences of breaking the rule should also be clear.

Other than that, you do not want to get into legal issues, I know of someone who reported his maid to the authorities and had to wait for a year before he could replace his maid because of court proceedings. If her contract is about to expire you may let her finish her contract and if you do not want her backk send her home.
