I am on an H1B and my wife is on an H4 (we are Canadian). We re-entered the US in June, but my wife's I-94 shows she was admitted under B1/B2 status instead of H4. We emailed the ATL deferred inspection site for a correction over three weeks ago but haven't heard back. Is the wait time usually this long, and is there anything else we can do to get her I-94 fixed?
The documents do not state if a three-week wait is normal for an email request. However, you do not have to wait for the Atlanta office to reply. Any CBP deferred inspection site or CBP office at an international airport can correct your wife's I-94, regardless of where she entered the country. USCIS cannot fix this specific error, so CBP is the only agency that can resolve it.
You can cross this worry off your list: you are not locked into waiting on the Atlanta office, because any CBP deferred inspection site can fix this error.
Because CBP issued the I-94 with the wrong B1/B2 status at the port of entry, CBP is the only agency authorized to correct it. USCIS rules state that if CBP issued the Form I-94, you must go to a CBP port of entry or deferred inspection office for the correction. You cannot use a USCIS form to fix a CBP mistake.
