The visa imposition was quite a complex process for us. We couldn't announce it too quickly, but we had to get ourselves organized. We hired a number of retired officers to support us in the initial stages. In anticipation, we did some local hiring without tipping anyone off that we were imposing restrictions. During the first few weeks, we depended a lot on all the resources in the mission. Even the ambassador was creating files for us at night and over the weekends. For the first couple of weeks, our staff in Mexico worked pretty much 22 hours a day to get it working.
I am glad to report that we are back to normal. We are now processing applications for people who will be travelling in December and January.
