The ongoing debate regarding the immigration reforms that the Trump administration is pushing for continues to divide the opinion of U.S. citizens. Restricting immigration will have a negative impact on the U.S. economy, according to Federal Reserve Chair Janet Yellen, who recently gave her testimony to the Senate banking committee.

"Labor force growth has been slowing in the United States. It's one of several reasons along with slow productivity growth for the fact that our economy has been growing at a slow pace," Yellen explained when asked by Democartic Sen. Catherine Cortez about the possible economic impact of restricting immigration, according to Business Insider. "Immigration has been an important source of labor force growth. So slowing the pace of immigration probably would slow the growth rate of the economy," she added.

Some legislators are also strongly against doing a comprehensive bill, but are instead pushing for better border enforcement.

"My conclusion is we're not going to be able to do a big comprehensive bill," Sen. John Cornyn of Texas told Bloomberg last November. "We've tried that. It just doesn't work. We need to secure the border and we need to enforce the law in regards to people with criminal records who are illegally in this country," he added.

In the same report, Sen. John Thune, the No. 3 Republican leader next to Cornyn, emphasized that the idea of a wall to protect the United States' borders should be seen from a theoretical perspective.

"There's the virtual wall, the technological wall, the real wall, the fencing — there are lots of permutations of this now being batted around," Thune said in an interview. "And I'm not sure exactly what it looks like. But I think border security and the wall are going to be the priority in any debate about immigration," he continued.

Trump has been very vocal and seemingly determined to push through with building a wall in the country's southern borders to prevent illegal immigrants from entering U.S. territory undetected. Senate Majority Leader Mitch McConnell previously revealed that he estimates the wall to cost at least $12 billion.

Trump has not revealed how his administration intends to fund the construction of the wall. He previously revealed several times that Mexico will reimburse the U.S. for the construction costs. The Mexican government has yet to issue a statement regarding Trump's announcement.
