I have some updates. Today I received the following:
12/19/2023 - Received in mail the I797 with the receipt number and the online access code
12/19/2023 - Received in mail the bio-metric re-use notification
I used the online access code to add the application to myuscis account. It shows two additional files (total four files). The first file is the .pdf of the receipt notice that extends my status by 48 months. The system said that all the three mails were sent on 12/14. However, I did not receive the receipt notice yet. Since that is the most important thing right now, I am hoping it is going to come soon.
The second file is a scan of some of the supporting documents that I sent. It is about half of the supporting documents that I sent in. The file name ends with the word part3. So I am assuming there are two other parts that did not show up in my account for some reason.
All these documents were generated by Vermont Service Center.
