What up with April 30, 2001?

So my mom was talking to my sister and I about something she filed for us in early 2oo1 that needed to be filed before the date in the title. She said she filed it through her employer or something, because she was legally working at the time. Anyway, I've looked it up and it gives me a bunch of immigration law jargon. I'm seeing an attorney on Tuesday, but I was wondering if some of you could shed light on what this represents?

Here you go. It's in plain English.

Wooooowwww, the most obvious of websites. Hahahaha, thanks bro/sis. Too good to be true, maybe? I guess I'll find out Tuesday...

You're welcome Hopefully you qualify under that program. I missed it by a few months xD

Good Luck. My family missed it by 6 months I believe.
