How did/do immigrants come to America with little money to their name and survive?

People often talk about themselves or their parents/grandparents/etc. coming to the US with something just like $20 and the clothes on their backs and working their butts off to build a life. How practically did that work? Where did they live and how did they eat their first few months of being in America? How long did it take to get a work permit?
