International student private loan for master at Ivy League - can’t pay it back, moved to Europe

Hey,

I took out a loan of 100k to pay for my tuition at an Ivy League. I moved to Europe and work, I can’t pay back the loan.

What happens if I live completely in denial and never move back to the US?

What are my options?

Can i go to jail or court?
