Hi - bring the documents that they requested on the test invite letter. I also printed out my travel history from the US border department but forgot to mention it to the CIC person. They had to check my husband's entries and exits with Canada Border Services as there were a couple of trips that his passport wasn't stamped. I wish I had remembered to mention to the CIC person that I had the US border travel history. Regarding your kids, how old are they? If they are under 14, then technically you don't have to bring them. My son is 13 and he just sat outside the hall when we did the test and the interview. As long as they don't need someone to look after them that should be OK. If they are little then as long as you have someone that can look after them when you are inside the hall you can bring them. But if they are younger than 14 then you can leave them at home if you want.
