I was completing my application and saw that they said on the Police Certificate section:
Does this mean that if over the course of my life so far I've taken a number of 2-3 week vacations to the US and those vacations add up to 6 months or more total, I would need a police certificate from the US?If you visited, worked or lived in a country for two months, left for a few years, then returned for four months, that counts as spending six months there. In this case, you would need a certificate.
