You were stating it as fact, with no mention of the fact that we have SEEN in this forum that some have encountered major trouble after continuing to work on an expired IEC visa. It's irresponsible to share your opinion as fact when you know there are a lot of people who believe you are quite wrong about the issue. People deserve to have adequate information to make their own informed decisions.
Some who continue to work after expiry of IEC apparently experience no problems. However, some DO. People should know that there IS a risk, as CIC is very, very unclear and inconsistent about whether or not IEC can be extended via implied status. Some may want to take that risk. For others, anything that could possibly put their PR application in jeopardy is unwelcome.
