There is no one answer to that. You’d need to check the terms of your visa. Sometimes, an internship related to your degree program is ok. But but it still depends on policies of the group that would take you on.
Your best resource is the faculty committee that endorses premeds as they set their plans. Their support is critical. As a current student, you don’t usually get far without them. By now, you also should have activities related to healthcare delivery, as well.
You don’t just do this in a vacuum. And you don’t just say, ok, I met requirements to graduate. Use your own college, dept, faculty, to learn the process and see how they assess you as a candidate.
