I have a friend who's going through her adjustment of status proceedings. She says they've asked her for her I-94 number from the passport she entered with in Miami in 2005. But she doesn't know it, can't find it, and there's nothing indicating she was given one (I'm sure she was).
There's also no date on her admittance stamp, only the date she entered. She never left, because she's raised a family with a US citizen whom she married back then, and isn't sure why it's so hard to find out this number, or where she can find it to complete application. Any advice?
