Can Hong Kong immigrants who are unable to enter the country on time due to special circumstances apply for an extension of entry? What procedures are required?

If you are approved and have received the one-way permit, it is recommended that you go to Hong Kong as soon as possible to go through the relevant procedures. If you do not leave the country after the expiration date, the one-way permit will become invalid, and you have canceled your account and there is no way to submit the application again. If there are indeed special circumstances, it is recommended to report the entry and exit at the place of residence with the corresponding proof of cause.
