DALLAS — Siddharth Jaganath wanted to return to India after earning his master's degree at Texas' Southern Methodist University. Instead, he built a new life in the United States, becoming a manager at a technology company and starting a family in the Dallas suburb of Plano.
"You start growing your roots and eventually end up staying here," the 37-year-old said.
His path is an increasingly common one: Immigrants from China and India, many with student or work visas, have overtaken Mexicans as the largest groups coming into the United States, according to U.S. Census Bureau research released in May.
The shift has been building for more than a decade and experts say it's bringing more highly skilled immigrants here. And some Republican presidential candidates have proposed a heavier focus on employment-based migration, which could accelerate traditionally slow changes to the country's ever-evolving face of immigration.
Mexicans still dominate the composition of immigrants in the United States, accounting for more than a quarter of the foreign-born people. But of the 1.2 million newly arrived immigrants here legally and illegally in 2013, China led with 147,000, followed by India with 129,000 and Mexico with 125,000. It's a sharp contrast to 2000, when there were 402,000 from Mexico and no more than 84,000 each from India and China. Experts say part of the reason for the decrease in Mexican immigrants is a dramatic plunge in illegal immigration.
"We're not likely to see Asians overtake Latin Americans any time soon. But we are at the leading edge of this transition where Asians will represent a larger and larger share of the U.S. foreign-born population," said Marc Rosenblum, deputy director of the U.S. Immigration Policy Program for the Washington-based Migration Policy Institute.
The national trend is evident even in Texas, where the number of Mexicans coming to the state each year has dropped by more than half since 2005, according to the Office of the State Demographer. In that time, the number of people from India coming to Texas has more than doubled and the number from China has increased more than fivefold.
While much of the discussion among GOP candidates has centered on illegal immigration, they have also touched on immigrant skill levels. Donald Trump has proposed kicking out people who are in the U.S. illegally before allowing the "talented" ones back in. Jeb Bush and Marco Rubio both have said that immigration should focus more on letting in workers the country needs rather than reuniting families.
Increasing the flow of highly skilled immigrants would likely have a big impact on those coming from India and China. The majority of them who are 25 and older who arrived within three years of the 2013 numbers had a bachelor's degree or higher, according to the Migration Policy Institute.
Without revisions in immigration policy, experts say the change to the overall immigrant population will be slow. One reason is that the number of Mexicans who become legal permanent residents is about twice the number of Indian and Chinese people who do, according to Michael Fix, the institute's president.
But a rising number of Chinese and Indians will become permanent residents, given the current rate of about half of people here on temporary work visas obtaining that status, Fix said.
Jaganath was among that group, inspired to come to the U.S. because the country is a leader in his career field. "That was a following-the-dream type of thing for me," he said.
