First of all, students should accept the fact that their behavior is wrong and stop copying immediately. Secondly, he (she) should actively communicate with tutors and course teachers, apologize to them, and strive for a second chance to finish homework. American universities pay attention to academic integrity. If students show a sincere and positive attitude, apologize to the academic community and are willing to improve, educational institutions will also give attention and support.
If plagiarism is confirmed by the university, students may be punished or even expelled. Students who are expelled should consult the university in time to find out whether their degree can be completed. At the same time, they can also seek help from the academic integrity center of the school and keep in touch with tutors and teachers. In addition, students can seek litigation or pursue others' infringement, but this requires legal knowledge and strict evidence.
In short, plagiarism is not allowed in any academic field, especially in American universities. International students should keep good faith, do their best to complete their academic tasks, and maintain good communication and trust relationships to avoid serious consequences.
