Yes you can be eventually expelled from school for cheating on your school work in high school.
However you usually do not get expelled for cheating in high school on the first offense but instead if it's your first time cheating in high school on your school work then you'll usually first be placed on academic probation and have your school work carefully monitored.
Then if you get caught cheating again then you will likely just be suspended from school for a period of time and then if you get caught a third time cheating on your school work in high school you'll usually be expelled from high school then.
You can then go to a different school in a different school district though if you did get expelled from school but you cannot go back to the same school you got expelled from.
Cheating in some schools may even get you expelled right away if they have a zero tolerance policy in those schools for cheating.
But most times you'll get a warning about the cheating on your school work before you actually get expelled or suspended from high school.
