Hello everyone - I tried doing my taxes online but its just too much tax jargon and blah...

Anyway...

I am a US Citizen, and my wife is not (not yet at least hehe ).
We both live in Mexico, though I do work in the US...
What would be the filing status? Head of household or Married filing jointly? I am the only source of income and I have been reading different things from different sites, I just don't know... I'm a computer type-person, not taxes... help would be greatly appreciated...

Thank you so much :)!

You can only file as married filing jointly or married filing separately. You can file joint return even when your spouse has never been to the U.S. and is foreign alien.
On joint return, you must both report worldwide income. Attach W-7 (ITIN application) with your tax return. Your U.S. Tax Return: Filing Status for Married
