From the IRS site:
Topic 853 - Foreign Earned Income Exclusion â General
If you are a United States citizen or a resident alien who lives and works abroad, you may qualify to exclude all or part of your foreign salary or wages, or amounts received as compensation for personal services rendered from your income.
If you are a United States citizen with a tax home in a foreign country and you meet the bona fide residence test or physical presence test, you may exclude up to $80,000 for the year 2004 and thereafter.
Resident aliens of the United States with a tax home in a foreign country may be eligible for the exclusion if they meet the physical presence test, or if they are citizens or nationals of a country with which the United States has an income tax treaty with an applicable nondiscrimination clause, and they meet the bona fide residence test. Specific guidelines for these two tests are covered in Topic 854.
The maximum annual exclusion is prorated on a daily basis if there is any part of the year that you do not qualify under either test.
