If u need to leave home for a very long period ( 2 months)VANESSAT, you can inform the immigration Dept that you have changed your address( For example your mama home address.) So, it is legal and the maid can work and sleep in your mother home.
Because, when I employ my maid, I used my mother address, I live with her in the first 2 months of my bb born. I moved back to my husband home after I work. I just fax the new address to them. Very simple.
Actually, there is no restriction how freq to change the address.Therefore, you can change back to your own home address after a long vocation.
Thanks for sharing junjun609. Very helpful information. Actually I just leave for several days with my family, however, I will also do the same as you suggested. You know as the employer of domestic helper in Hong Kong, will need to keep the awareness to avoid against the Labour/ immgration law anytime.
