In Singapore, a PR status is renewed every five years depending on whether a person has made significant economic contribution. The criteria is subjective. It is speculated that a PR residing overseas mostly can retain the status if he has volunteered CPF contribution, and if he happens to work for a Singapore enterprise outside Singapore. Lest we forget, like HK, Singapore PR status is for sale. As “little” as a few million, PR status can be bought for the whole family. It is a PR investor scheme administered by EDB.
