Not really a question but rather some information for all who have submitted a HK PAR and have later realised they got something incorrect. Please note that an existing valid PAR cannot be cancelled so you cannot resubmit a PAR application, however you can amend the existing PAR by visiting the link below, and you will be taken to a page where you can amend your details.

This means that even though you cannot cancel and resubmit a new application, you can modify the details in your current application to correct any mistakes.

In summary, while a valid PAR cannot be canceled or replaced with a new application, the amendment function provides a way to correct mistakes and ensure your details are accurate for your trip to Hong Kong.
