Hi,
your existing helper has 14days limit from the termination date to stay in HK, some domestic helpers starts to look for new employers within the 30days termination notice given to them (if employer provides 30days notice before termination) and some just have to find one within the 14days (if they're terminated by employers on the spot or without 30days notice).
if you or anyone you know need assistance with domestic helper concerns, processing, documentation etc, you may whatsapp message me at 93115905 Thessa
