The Trump administration is stepping up pressure on Congress to curb chain migration, saying it presents a threat to national security.
President Donald Trump wants to stop legal immigrants from being sponsors for members of their extended family who want to move to the United States.
Immigrants approved for family-based visas have dropped to the lowest levels in a decade -- and that's without any new limits from Congress.
Norman Adams, co-founder of Texans for Sensible Immigration Policy, says there's less incentive to come here, especially from Mexico.
Adams agrees with Trump, however, that a solution needs to come from Washington.
Specifically, Trump maintains that chain migration allows a single immigrant "to bring in dozens of increasingly distant relations," with "no real selection criteria."
His administration has taken several measures to look at legal immigration – even though the more visible steps have been the president championing a “big, beautiful wall” along the Mexican border and more arrests of people living in the country illegally.
There also has been an slowdown in adjudications of family-based visas, or I-130s, according to Reuters.
