US Immigration from Taiwan

• May 11: I received a mail saying USCIS recalled my green card due to the error of the alien number on my green card. ( I checked my case # on the website. It said USCIS recalled your green card. )
• May 12: I sent back my green card along with the notice to the PO Box listed in the letter.
• May 13: Mail was delivered
• May 25: My case status changed to card was destroyed : On May 25, 2021, we destroyed your card for your Form OS155A, Immigrant Visa and Alien Registration, Receipt Number IOE....., because the Post Office returned it and we did not hear from you. You must file a Form OS155A, Immigrant Visa and Alien Registration, with the correct fee to obtain a new card. If you move, go to www.uscis.gov/addresschange to give us your new mailing address.

Does it mean they received my old card and destroyed my old card? But why does it also say we did not hear from you. You must file a form OS155A ?

Does anyone also have the similar experience of green card being recalled? Thank you!
Btw my green card was issued in Feb, 2019.

Hi

I just received my NOA2 and noticed that there is a validity date on the notice - it is valid for the next 4 months. The current processing times show that it will take around 4 months for my application to go through the NVC and be received at the embassy. Is there any issue if the NOA2 is no longer valid by the time NVC is done processing? Should we plan on the interview to occur within the NOA2 validity date?
