Hey doji, I have a bad feeling about cross chargeability after y'day's conversation. It seems to me that even if our cases were accepted under cc, the actual case file doesnt really have a big red flag on it that says 'I'm current - process me !', y'know.
I guess you could start by calling them. My case is at the NSC so I'm not sure the same number combo works for Texas - worth a try - here it is - the 1800 number, then 1, 2, 2, 6, 1, your receipt number, listen to the message, then 3, 4 to talk to a rep. Ask them if you have visa numbers and mention the cc clause and ask if they can flag your case as being current.
If calling doesnt help, maybe talking to an IO at the Infopass would be a good idea. I called NSC again today and the rep did confirm that the case had been flagged to be picked up by an IO.
Hope that helps,
vik
