going to USA
patio11: Mariano, unless you have left out important information such as "Although I grew up in Argentina I am a U.S. citizen by virtue of being born in the United States", you lack legal permission to work in the United States unless you get a visa which permits it prior to arriving in the US.  I'll just give it to you straight: it is not likely that you will be able to do this in anything like the timeline you are currently planning.Without legal permission to work in the U.S., you will find it extraordinarily difficult to find reputable employment.I would counsel against illegal employment -- when I was young and stupid I worked on a cash basis for a man who "didn't want none of that OSHA paperwork nonsense", and I was forced to quit the job after he threw a 20 lb. pipe at my head.  (Cleaning oil pipeline components with a toothbrush is, by the way, every bit as fun as it sounds.)
