These are just a few links I currently have. I will post more in the near future.
The official documentation and laws for immigrating to Argentina can be found at Migraciones (site is In Spanish).
To get your CDI you'll need to visit the AFIP office for your domiciles jurisdication. Then you'l visit that office to declare your domicile.
Argentine consulates are located in most of the major cities across the U.S. To find your nearest consulate simply look for the location nearest to you. I've added website links wherever they were available.

Chris, If you're a U.S. citizen you don't need a visa to enter the country. Upon entering you will be given a 90 day tourist visa.
Key questions: Do you have a job already or do you think you'll have one? If not then are you planning a business? These are a couple of key questions that will help me get you pointed in the right direction.
For a long term move you should begin to look at what type of visa you would live on. There are several types that I outlined in my post http://movingtoargentina.typepad.com/my_weblog/2006/01/visas_and_visa_.html
There are other visas available such as student visas but it's hard to give you more information without knowing what you are planning to do down there.

Hello,
I stumbled on your site while trying to find logistical information (visas, length of stay, etc) i need to know as I'm considering a move from the U.S. to Buenos Aires. I saw your Visa & Documentation Links page, and the link to the official documentation and laws site, but simply put there are just way too many words on there. my question -- what exactly did you need to do to be able to move down there? what hoops did you have to jump through at the consulate? I just got back from Brazil and got my 90 day visa, but noticed that I didn't need one to enter Argentina. What is really required for a long term move???
Thanks much for your help.
