Passports and documentation are a relatively new concept. Before 1920 or so, you would just show up in the USA for a new life, and if your skin color was the right shade of white, no one would stop you (otherwise you might be interned or otherwise sent back). All immigrants were undocumented back then.
Today, you show up with a passport and a visa, which is easy to get if your skin color is the right shade of white. Somethings never really change.
