回複:I am in Chicago.
H1B will be expired on May, 2009. The lawyer asked for extending, and then found the problem from I-94: 2007, 10, 27.
Just take your original H1b and error I-94 and all other relative docs, you will be corrected with a new I-94.
It is not that complicated thing that you have to do with a "lawyer".
You can do it yourself.
Good luck
