@mtlucero5 the above answer ( that you can use Foreign Earned Income Exclusion ) assumes (a) you are a US citizen / Resident ( Green Card ) and (b) that you meet the Physical Presence Test ( absent from US for at least 330 days in a continuous 12 month test period). Also you can claim foreign tax credit on income taxes paid on not excluded income that has been taxed by a foreign taxing authority. As a US citizen/Resident you have to file a federal return as long as your world income ( before foreign earned income exclusion ) is equal or above the filing threshold for your filing status.
Does this answer your query or do you need more clarification ( in that case please provide your dates of foreign stay, your employer { US or foreign entity}, other benefits provided by the employer, was your family with you etc. etc. )
