Hi there, I understand your frustration here but you need to make it clearer here before we can help you with any information...
but before this, I think the following might be useful to you:
1. This is what I found by observing HKVO’s behaviour. They usually send an long email, the one you posted here, to everyone whose file gets transferred to them. This to me serves a kind reminder to us that if we have already known we miss or forget to submit certain vital documents that are listed on the email, now it’s a good time to submit them to the VO. Same goes to the situation where you have updated information on those forms, for example, changes in family members on the additional family information form.
my suggestion is, you submit those forms and documents anyways, even though you know you have already done so, provided that you have additional copies and it’s easy to get everyone sign on the forms.
2. If you know you forget to submit certain documents, contact HKVO and submit the documents via web form. It doesn’t matter if you receive this email reminder or not, missing is missing. They will find it out eventually... they will normally respond to web form inquiry within 20 days..
Hope this help you a little bit my friend
