Mrs.Iryn, yes, you and your indonesia maid don't need a visa for Macau & Hk, you two just need a visa for Zhuhai, you both can apply for visa on arrival at the entry port of Zhuhai because Zhuhai, as a special economic zone, has the right to issue a visa on arrival which valid for only 3 days in Zhuhai. Your Indonesia maid can come to Singapore to take the flight to Macau. As I know, Indonesian passport holders don't need a visa to Singapore, right?

Thanks Mrs Linda for your reply.

I only need to go to Zhuhai for 1 day.
applying the Visa on arrival ? On the spot apply , how long it takes to be ready ? How much is it ?

Mrs.Iryn, yes, you can apply for the visa on arrival, it takes about 10 minutes, it costs about 100 Hk$

For Macau , Hong Kong & Zhuhai .. How many types of currency do i need to prepare ?
Oh 10 mins & HK100 .. so fast & cheap .. but is there any case that they will reject the application ?
Cos i went to the Malaysian travel agency to enquirie the china visa for my indonesian maid , they request me to write a letter & many other other documents, in order to support the application.

Mrs.Iryn, yes, it is a little hard for you Indonesian maid to get a visa on arrival. I went to China on 10 december, I went by train, I found at the China side just before the immigration a stairs that goes up and there is a small office where I apply for a China Visa. This visa is only valid for 5 days and it’s a single entry. It takes about 10 minutes and I'm on my way. no photo needed. It costs me 100 HK$. I hear for some nationalities, HK$ 150 is charged.
