Specialist help with US student loan repayment rules and US taxes?

Does anyone know of a good resource for specialist help with US student loans?  I am probably going to have a very hard time finding a job anytime soon, and I stupidly have an enormous loan debt.  I am looking at applying for the new income-based repayment plan, but I'm having a hard time finding any information that is relevant to people who live overseas.  But the information I have found so far wants to know about the family Federal income, which doesn't apply in a straightforward way because DH is British and is not liable for US taxes.  I've been an unemployed student for the last several years, so I haven't actually filed taxes since I got married, but I don't know how I should file when I next do so.

Are there any good legal resources out there?  What should I even be looking for?  I'm really clueless about where to begin with looking for information.

You might want to check out this info on the IRS website - they could probably help with the tax question.  There's even a walk-in office in London.

You should file married filing separately if you're husband is not American - but you'll probably still need an ID number for him - you could establish your zero income that way.  I would think that you'd want to contact your loan servicing company to arrange for a change in payment amount.  (Who sends you the bill) As long as it was not a private student loan you should be able to either lower the payment through the payment plan you suggested or even get a furlough that would let you have 6months off while you're unemployed. (Depending on the type of loan you may still be charged interest that will add to your principal at the end of that period.)

In my case, my loans were services by Sallie Mae - so that's who I contact - but I also had some federal direct lending loans and then I contact federal direct lending to arrange the payment plan.

Good luck!
