Sixty percent of Hispanic adults born in the United States say they want immigration levels to be reduced or kept steady, according to a Gallup poll released last month.

That's compared to the 39 percent of U.S.-born Hispanics who say they want to increase the number of legal immigrants allowed into the country.

As for Hispanics not born inside the U.S., 62 percent say they want immigration levels to be reduced or leveled. Only 33 percent of those want immigration levels to be increased.

Gallup's findings are likely good news for Republican front-runner Donald Trump, who has made pro-American immigration reform a centerpiece of his campaign. Rather than continue encouraging companies to bring in foreign workers through the H1-B program, Trump says his plan will force companies to give the coveted STEM jobs to the existing domestic pool of unemployed native and immigrant workers already inside the U.S.

On the other hand, former Florida Gov. Jeb Bush, who could be viewed as Trump's main establishment rival in the GOP presidential field, wants to invite more foreign blue-collar and college-graduates to compete for jobs already sought by American workers, notes Breitbart.

In another recent Gallup poll, 20 percent of respondents said they will only vote for a candidate who shares their views on immigration, with an additional 60 percent saying that a candidate's immigration policies will be one of many important factors taken into account when deciding whom to vote for, as HNGN previously reported.

The U.S. government grants green cards to nearly 1 million foreign nationals each year. Another 1 million migrant workers come each year, along with an additional 300,000 illegal immigrants, according to Breitbart.

Many voters are concerned that the significant inflow of foreign workers are preventing the 4 million young Americans who enter the workforce each year from finding adequate employment. "This inflow gluts the labor market, drives down wages, increases taxpayers' costs, but also boosts corporate profits and Wall Street stock values," explains Breitbart. "Despite high unemployment and low wages, the federal government does little to keep illegal migrants from taking Americans' jobs, including the lower-skilled jobs sought by most Hispanic Americans."
