Mr. PJIANG,
I have got my green card. When I organized my files last night, I found that I lost both my original I-140 approval notice and my original I-485 receipt notice. I still have my I-485 welcome notice and I-485 transfer notice.
Is it a serious problem for losing I-140 approval notice? Do I need to ask for a replacement from USCIS?
Thank you very much.
