Actually, there is a website to search for US travel records, you might kinda feel there is no privacy after you try itGuys, I've been to the US on vacation twice in the last year but never stayed more than 10 days in each trip. The US does not stamp our passports when we exit the country and when I arrived in Brazil I did not get an entry stamp either. How can CIC determine that I did not stay in the US for more than 6 months?
Here is the link
