Finally, My I-485 was approved at TSC

After over 5 years long time waiting, I finally got the emails from USCIS.

Information about my case:
EB-1a
I-140 filed Feb, 2003, approved in April 2004
I-485 filed June, 2004, got the emails (for me and my family) of “card ordered” and “welcome notice” today(02/27/08).

FP two times
Ref. for medical examination in Dec. 2007
I wrote to first lady, senator and congressman. But I don’t think it help.
Even yesterday, Senator’s office called me told that they can not do anything if background check is not clear. I think the MEMO works now.

Special thanks to XBT and other persons’ answers here.
Good luck to all of you who are waiting GC!
