How good is an internship in Duke Medical Center?

<p>I am International student. I am Junior at UNCC - EE Major.
I have got an Internship at Duke University last year as the only job experience I have here in US.
I really want to stay here but I am not sure If I can easily find a job after I graduate so I am wondering if this Internship is going to help me?
Or should I add a minor or something so I get better resume?
I wanna clear something, Its not really easy for me to find a summer/general job or even internships because I am on studying visa
Thanks, </p>

<p>An internship will be much more beneficial in terms of finding a job than a minor would.</p>
