Depending on their level of acculturation (ability to adjust more easily to the customs of the new/changed culture), the immigrants will vary in their economic impact. Typically, as a group, each new wave of immigrants tend to occupy the lower rungs on the economic ladder.
However, if the skills they bring from their home countries more closely match those needed in the U.S., their economic status would fare better.
With new cultural norms influencing the general U.S. culture, there is the development of new businesses to satisfy new markets. (Have you eaten at a Chinese restaurant lately?)
However, you need to decide what eras and what groups you are going to cover as examples of their imact.
