Probably the desire to apply for a green card. Technically you are not supposed to do this in an E3 because it demonstrates immigrant intent, and the E3 doesn’t allow this. I know people who have done it successfully but I also chose to get an H1B before putting in a green card application years ago, and I would be even more cautious in today’s atmosphere.
