What college should I choose as an Engineering major?

Let’s suppose that you were denied a visa and needed to return to South Korea. Would you be able to pay off the $50,000 debt working in South Korea?

Since the debt is involved with my parents, not financial institutions, I am not in rush to pay for it (they said payback when it’s possible). However, I doubt that I can pay back the debt working in Korea; not because I can’t, but it will take a significantly long time to pay back that much money with Korean wages.

Relying on immigrating to the US is a dangerous plan, particularly when debt is involved.

Do you have any suggestions for my plan then? I don’t really want to consider the option to just go back to South Korea and attend colleges there because I would have to spend another 1 or 2 years studying for the college entrance exam (which would be difficult since I haven’t studied in Korea for almost 6 years).
