I opened a Roth IRA in 2000 and have been contributing the maximum allowable for each year. I am a dual citizen of the U.S. / E.U. and as of 2009, I will be living and working overseas (presumably England) but NOT for and American company.

Is there a way I can still fund the Roth if:

1. I am not filing a U.S. tax return?
2. I file a U.S. tax return, but do not earn over the foreign income exclusion credit?
3. Send after tax money to the states from overseas, then pay taxes again (U.S. this time) on that "income"?

If 'no' to the above scenario's, is there another way I could fund a Roth IRA I'm not thinking of or listing here?

Thank you in advance for all your help.
