I have about $50k left on my student loan and about $15-20k in cash on hand(I saved!).

I'm leaving my overseas job and going back to America. Given the poor state of the US job market, I'm worried my $15-20k will dry up before I can find gainful employment.

I'd rather just try to borrow another $10-20k from my parents and negotiate to settle my Debt in lump sum rather than pay over 10-20 years.

My loan is with citibank who says they don't officially do this with student loans. Has anyone managed to negotiate an upfront, lower payment of cash to settle a debt instantly?

Do I have to enter default and wreck my credit score before I can even bring them to the negociating table?
