In times past, immigrants to this country who came here legally were required to formally swear they could not allow themselves (their sponsor, if any had to also swear)to become a public burden. It seems to me they violated this now-defunct requirement.
If there was a valid condition on his residency... then yes he ought to be deported.
It ought to be something like this sort of formal pledge, however, not that we just don’t like him becoming a bum because we prefer to home grow our bums :-)
We immigrated here in 1952 and that was the law. Immigrants had to have the promise of a job, and American sponsors who would cover their expenses (medical, housing, etc.) for the first five years should the immigrants require assistance.,.near impossible requirements. Fortunately, my Dad, brother, and mother arrived at ll:00AM and all hit the streets, on foot, by noon looking for work. I went to the home of our sponsors (I was 12). Both parents and my brother never arrived home until after 5:00PM, all getting jobs and being employed that same day. And fortunately, I’m 75 now, none of us were ever a burden on our sponsors or the government. But it was a different America then.
