A comprehensive study on immigration's impact on the U.S. by the National Academies of Sciences, Engineering and Medicine in 2016, looks at the broad fiscal and economic impacts of immigration. On the drawbacks the new immigrants can lead to lower wages for earlier waves of immigrants and high school dropouts. It can also burden government finances, education budgets at local and state levels. On the plus side it leads to more innovation, entrepreneurship and technological change in the economy. Other facts that are new in the report and run against the popular narrative are that 53% of immigrants had at least some college, including 16% with graduate education, as of 2012- which explains the technological impact of being open to immigrants. It is this that helps lift overall growth says the report- "the prospects for long run economic growth in the United States would be considerably dimmed without the contributions of high-skilled immigrants."

About 42.3 million immigrants live in the U.S. in 2014, 13% of the population, increasing from 24.5 million or 9% in 1995. Unauthorized immigrants doubled in this period to 11 million. 

A surprising result considering the popular idea of anti-immigrant sentiment in the U.S. is that a WSJ/NBC poll shows 54% of respondents saying immigration helps more than it hurts. In 2006 only 45% to 42%, considered immigration as beneficial to the country. Immigration is an issue today even though in recent years the large scale deportations under the Obama administration and difficulty finding jobs have reduced the flow of immigrants - since 2009 about 300,000-400,000 new unauthorized immigrants arriving and similar number leaving.
