I have a maid from Indonesia. Most of the Indonesian maids prefer to work in nearby countries like Malaysia, Singapore, and Brunei because of the similar language. It is much easier for them to understand the instructions from their employer and as such can avoid making unnecessary mistake because of language misunderstanding.
The maids have a choice to work in other countries like the Middle East countries. The pay is much higher but the maids must understand English or Arabic. The good thing about working in Middle East is the maid's salary can be in kind. The maid can ask the employer to buy gold bullion for her instead of paying cash to her. I think this is a better deal for the maid if the maid does not need to use her salary as gold price keeps on increasing. If the maid has to send back money to her family, then this salary deal is not appropriate as it is risky to send back the gold bullion to their own country.
I was further told that sometimes the maids in Saudi would never seen her employers face throughout her employment period as the women would wear burqa and the maid would not be allowed to see the male employer.
