回複：It's always original I797.

Thanks a lot. That's what the diretor told me today. I can get a replacement if the original one is lost. It's just requires some fee. I decided to send the bottom portion instead of whole thing since the bottome of the form is for the purpose of visa application and the top is for the records. I wish this will help. Anyway, my daughter and I appreciate your help very much. Merry Christmas.
