Hello friends,
Thank you so much for your help and your input. So when we went through Tijuana, all that the Mexican agent asked for was her b1/b2 visa. It was not swiped or anything through a computer, and the agent just confirmed that it was still "valid". We did give a call to the US Consulate in Manila, and we were told that the Visa was in fact active. Apparently the best place to call to see if your visa is active is to call the place that issued the visa. There was absolutely not issue going through the border. it was a lot of headache and stress for nothing.
