I really hope that you have citations for that. Not saying that you're correct or incorrect (I have not personally gone out of my way to find landscapers and determine whether they're legal residents or not, so I obviously have no data points to contribute), but in the absence of some sources - or at the very least a few anecdotes! - it sounds like you're making sweeping generalizations about groups of people, possibly based on their appearance.
