Mistake on I-94 at POE - ways to correct?

[sundarpn]

Hello,

When entering via Washington DC last month, the CBP officer incorrectly wrote the classification as H1-b instead of H-4 on my wife's I-94.

How can we get this corrected?

thanks.

You can go to the CBP office at any POE and get it corrected. Last week my friend corrected his family name and first name at the same POE office..
