以"永久性離開香港"拎強積金,拎完and離開左香港,咁最快可以幾時返香港最好?

you can come back to Hong Kong anytime. However you can never use the same reason to apply for early withdrawal of the mandatory part of the MPF contributions. This reason can only be use once in a lifetime. but the authority will not care when you will be coming back to hk as they trust that this departure that you have declared under oath (part of the procedure as this will ensure that the member is swearing for the truth) is a one time and long term decision.
