Visa appointment at Tijuana (Mexico) US embassy?
Hi,
I am trying to get a visa appointment at Tijuana US embassy in Mexico. I paid 8 $ and got a PIN. I am trying to get a online appointment date but saw that no appointment date is available till December 2008. In the calender it is written ” not available (red stars)and some days as “not opened (grey stars)”. Will they open the “not opened” dates lately for visa appointments? It looks bit strange as I am unable to get an appoinment in coming 3 months. Can any one help?
I had made an appointment at the Tijuana embassy for someone a couple months ago and was able to get it within six weeks. We needed to change it, though, and when I went back to reschedule, there were some new dates open. I don’t know whether this was because they opened more dates or because people cancelled. At any rate, I think you should just check the calendar frequently to see if anything else opens up.
