Hello Mr. 8,
I just checked her W-94 and the expiration date is 07/04/2016; I wonder whether it is very risky if I put her fly ticket on 07/04/2016. You know, it is possible that her fly can be delayed. I mean if that is the case, can I use that excuse to argue with USCIS for the validity of her B1/B2 Visa?
Thank you very much!
