I-797 never received but received wife's Packet 3 and my Step-daughter has not

[kel&ruth 0]

Ok so I have been stressing like crazy. I was stationed in South Korea and submitted petitions for my wife and step-daughter via the US Embassy in Seoul and we ask for the files to be transferred to Manila because I was leaving for assignment in Hawaii. Both petitions were submitted on May 6, 2015. I also elected for electronic notice and never received any emails. I moved to Hawaii in July and still never received any update about our petitions. So I decided to contact the US Embassy in Seoul to see what was going on. When I told them my case I was told that both my petitions were approved 9 June 2015 and our approval notice was sent to an address that the Army prematurely shut down without a backup plan. So the Embassy in Seoul sent me another approval notice but I only received my wife's. A few days later my wife received her Packet 3 but nothing for my daughter. I contacted Manila and they said that they don't have my step-daughter's file in their systems and elevated a concern to NVC. I contacted the military hotline and they also told me that they don't me nor my family in their system. I just sent an email to the NVC concerning all of this. I was reading more into the process and came upon the NOA (I-797) that I never received. Are the I-797 needed for anything else in the Visa process and have anyone had an issue like mine where they only received one PAcket 3?

Because you initially field your petitions at the USCIS field office in Seoul, contacting the NVC is a pointless exercise because they are not involved at any point when a petition is filed at an overseas USCIS field office.

I-797 receipt and decision notices are not needed for anything, they are for your records only (i.e. the process will not be delayed due to not having an I-797).

If the Embassy in Manila does not have a file for your step-daughter, then the place to follow up would be with the Embassy in Seoul, not the NVC.
