I know and understand completely what you mean ...I did my medical exams in Guyana with my baby girl and I had to travel to my main capital habana because there is not a direct fly from my province holguin..later to Panama and Guyana after..and I will do it again because the embassy of Canada closed in my country and they do just finger prints...and passport stamps ...I am from Cuba as you could assume already and for us is even harder...we apply in April 17 2019I'm the same...application received Jan 7...confirmation it is in Mexico Oct 23...but we have heard nothing else. I just need to be prepared but I didn't think it made sense to have the interview in Mexico. It seems a little much to make people travel to another country for an interview
