so my parents are in Canada and the letter says they must leave Canada to take biometrics, I called the agents and they said no work around, your parents must leave Canada to take biometrics, for some unknown reason they keep saying you should not go to USA to take biometrics. When asking repeatedly why, the agents just say if you have legal status in USA such as citizens or green card then you can do there, otherwise you should go to any country that you can legally enter. I said they can apply for visitor visa, but they keep saying same thing. Nearest place to take biometric is Mexico city and it costs at least 3000 for 3 of us to go there for a day to take biometrics. Not to mention that not many direct flight there and most connect in USA which requires transit visa. Mexico requires appointment to take biometrics and the slots are not available all the dates so it is very hard to arrange a trip there, cost can be over 4-5K for direct flight for 3. So very upset with this burden, not to mentioned my parents just recently did biometrics for super visa.
