我老婆H-4 是否过期了，该怎么办？？？

Hi, fridrends,
Until yesterday, I just
noticed that on my wife's visa, there is no expiration date as I have as 5.30.2006. And on
her I-94, the officer marked "until" with "Feb 18, 2004", which is the date of
her entry visa expiration (single entry for 3 months). I thought that was a
mistake made by the officer.I have heard many times that H-4 has the same
expiration date as H-1, so at that time I didn't pay any attention to that.

Now I am planning to do a H-1 transfer, and just noticed that.

Do you think I need and How to fix it now?
