How can a Hong Kong wife’s mainland husband apply to live together in Hong Kong?

The Hong Kong wife’s mainland husband and the Hong Kong husband’s mainland wife apply to live together in Hong Kong in the same way. They bring their household registration book, ID card, several 48x33 ID photos, marriage certificate, and Hong Kong wife’s ID card. With a copy of the return permit and a letter from your Hong Kong wife (it is best to sign the mailer's address on the envelope), go to the Exit and Entry Department of the Public Security Bureau where you are registered to apply for a one-way permit.
