Visitor Visa Appointment while waiting for approval correction

[yvsrinivas]

Hi,
I applied for L1A Visa extension for 7th year. USCIS website shows approved for the case. But it seems USCIS did some error while approving. They sent approval like a fresh approval notice. I mean they did not send new I94s. So my employer is following with USCIS on this. Meanwhile my in-laws have visiotor visa appointment in on Oct30th. Do you know what is the document they need to carry to prove my status valid?

Thanks in advance.

when is your curent I94 expiring ? or is it already expired?
If not expired a copy of valid approved petition and I94 should do.
