Hello there, hellothere!
Welcome to our ALL SPAIN Message Board!
pedmar's advice is the best one. Contact your local Spanish embassy or consulate in the USA and ask them. They'll have more details than we can provide here. Plus, these details change from year to year. Hopefully you can find their website and an email address so as to avoid waiting ON-HOLD on the telephone.
Take a look at the front page of http://www.ciudadaniaespanola.com/
(only in Spanish). I don't know how current or accurate this information is, but can give you a good idea of what's required for "Los Nietos de Españoles."
Keep in mind that work, work availability, working conditions, and salaries are FAR from the standard you might have enjoyed in the USA.
Best of luck!
