8老师，请问还需要提交什么材料

2020底的时候我在NVC网站提交了以下材料for 广州F2B 移民面试：

I-864 Sponsor，I-864A Household Member with Tax transcripts and W2s

PASSPORT BIOGRAPHIC PAGE

PHOTOGRAPHS

Birth Certificate

Police Certificate

当时收到Message显示All required applicant documents have been received and approved.

Later in Aug 2022 after receiving a notice letter that an immigrant visa interview will be scheduled for the beneficiary, I thought it’d better to update tax transcripts and W2s for newer ones given the original had been submitted two years before. So I did. Then on 22-AUG-2022, I got message “NVC cannot review your submitted documents until we have received all of the required documents”. 一直到现在都是这样。

我现在糊涂了，不知道还需要交什么材料。请问8老师，多谢多谢
