Seventy-six percent of registered voters polled in the March 19-22 survey agreed that the current surge in immigrants at the border is a crisis that needs to be addressed immediately.
By contrast, 24 percent of respondents said the situation can be dealt with later.
Along party lines, 87 percent of respondents who identified as Republicans, 73 percent of those who identified as independents and 66 percent of those who identified as Democrats said the current situation at the Southern Border is an urgent crisis.
The Biden administration is facing mounting criticism of the border surge.
According to documents obtained by Axios, the number of migrant children being held in the U.S. Border Patrol custody for longer than 10 days has quadrupled in the past week.
The most recent Hill-HarrisX poll was conducted online among 2,858 registered voters. It has a margin of error of plus or minus 1.83 percentage points.
President Joe Biden's border czar is scheduled to travel to Mexico on Monday to meet with officials about the influx of migrants coming to the U.S.-Mexico border seeking asylum, as the White House maintains there is not currently a crisis at the border.
Roberta Jacobson, special assistant to the president and coordinator for the southwest border, is traveling to meet with Mexican government officials. She will be accompanied by Juan Gonzalez, special assistant to the president and senior director for the Western Hemisphere.
They are expected to "engage with Mexican government officials to develop an effective and humane plan of action to manage migration," National Security Council spokeswoman Emily Horne said in a statement.
Jacobson was the U.S. ambassador to Mexico between June 2016 and May 2018.
White House press secretary Jen Psaki on Monday refused to call the situation a "crisis." House Speaker Nancy Pelosi has previously labeled it a "humanitarian crisis," while Republican lawmakers have called the situation "Biden's border crisis."
"Children, presenting at our border, who are fleeing violence, who are fleeing prosecution, who are fleeing terrible situations is not a crisis," Psaki said. "We feel that it is our responsibility to humanely approach this circumstance, and make sure they are treated and put in conditions that are safe."
The trip comes as the Biden administration continues to struggle with the increased number of migrants trying to pass into the United States at the nation's southern border. They're receiving pressure from lawmakers on both sides of the aisle to address the situation, which many Republicans are calling a "crisis."
Biden and top administration officials have repeatedly maintained the border is closed, but the government is holding migrant children in facilities because officials say it would be too dangerous for them to make their journey back to their home countries.
