When you purchase the policy, you may not know your maid’s arrival date in Singapore yet, but you need to have the policy ready when she arrives in Singapore for the maid to be allowed into Singapore. There also could be cases where the maid’s work permit may be extended and in this case, you will need valid bond and insurance for the extended period. That is why there are 2 months additional to the standard work permit period of 12 or 24 months.
