I need assistants with choosing an ethnic group to learn more about. I need help with the research on how the group originally came to the United States? if there were or are still any challenges this ethnic group endured while coming to the United States. If there where any challenges or successes with assimilation.

Please provide me with references so I can review where information came from, while creating my presentation.
