I think you should write to MOM and explain your case to them. I personally feel this maid should not be allowed in to wk in sg. Imagine if she us taking care of baby.
The agent is so irresponsible saying it is common.
I dont think it is common bc I had 3 maids of 2 diff nationality and I never come across a chk up with VD. My maids are taking care of my 2 kids.
My advice is to report the agent & maid to MOM. Then send back the maid bc you dont want another sgporean family to suffer.
