What surprised me learning about the immigration activity was when people passed through Ellis Island how they check them to make sure they don't have diseases. I wonder why they started the immigration through islands and not a different way to get them here in the untied states? It started for immigrations to try to have a better future but they had to go through the check out station to make sure they had no diseases.
