Since 1970, (click here) the foreign-born population has continued to increase in size and as a percent of the total population. Today, the majority of foreign born are from Latin America and Asia. Considerable differences exist among the different country-of-birth groups in various characteristics. About 1 in 4 children under 18 in families have at least one foreign-born parent....
Nikki Haley was born on January 20, 1972, (click here) in Bamberg, South Carolina, to Sikh immigrants. The Republican entered politics at a young age, and served in the South Carolina House of Representatives for several years before becoming governor of the state. In addition to being the first female governor of South Carolina, she was the first Indian-American to serve in the role, and the second Indian-American governor in the country, after Bobby Jindal of Louisiana. In 2016 President-elect Donald Trump picked Haley to become the United States ambassador to the United Nations, and she was confirmed for the position in January 2017.
This is from Pew organization:
...More than 41 million immigrants (click here) lived in the U.S. as of 2013, more than four times as many as was the case in 1960 and 1970. By comparison, the U.S.-born population is only about 1.6 times the size it was in 1960. Immigrant population growth alone has accounted for 29% of U.S. population growth since 2000....

On Page 16 of 22 is a graph entitled, "Percentage of Population with a Bachelor's Degree Who Are Foreign Born by Field of Degree: 2010 (age 25 and older)
All Bachelor Degrees held by Foreign Born in the USA was 16 percent.
All Science and Engineering Degrees - 21 percent
Engineering - 32 percent

Physical and related sciences - 24 percent
The USA relies on its birthright citizens for its brain trust.
Page 19 is a graph entitled, "Occupation by Nativity Status and Country of Birth: 2010 (Civilian employed population 16 years and old)
The majority of the birthright citizens born to non-citizen parents are employed in Management, Business, Science and Art Occupations with median incomes of $51,209 a year. The only birthright citizens that are not employed as a majority in professional jobs are those from Mexico with annual incomes of $16,910. The highest poverty rate of these groups is Mexican birthright citizens.
There is no explanation for this group's struggle, but, it may be that they have to work early, such as 16 years old, because their income is needed for their family. The Mexican birthright citizens need to be understood better. California may have better statistics on this group and why they are not achieving as other groups. They obviously are disadvantaged, but, the question is what is the disadvantage and how can they overcome it. It is probably the ability to purchase a home.
The United States of America does not have the highest rated schools in the world and it has become dependent on the Green Card to enhance it's brain trust. I strongly suggest education in the USA has to improve immensely before there is even a debate about birthright citizenship.
