回複： If it was a sucessful one, it

What do you mean if it is a successful one? I want to order NIW kit, are there different versions of it? I found one place in NY called "Green Card Apply Service" sells it for $79. Is it the place everyone was using or are there different places and different versions? Thanks a lot!
I put their website here, just in case anyone else also wants to find it.
