I would like to file my income taxe with earned income tax credit, is there a office I can go to in New Orleans?

You can look for a VITA site close to you where they would file your return for free
Find a Location for Free Tax Help (http://www.irs.gov/Individuals/Find-a-Location-for-Free-Tax-Prep)
Or you could use tax software that offers free filing for low income/EIC eligible taxpayers.
Turbotax offers the Freedom edition, available in mid-January: https://shop.turbotax.intuit.com/taxfreedom/turnaway.jsp
But I guess there are others too

Try the IRS website (link below) for a list of free tax preparers.
