With Customs and Border Patrol agents reporting a rising number of family units crossing illegally into the United States, the American public school system is struggling to provide educational services for the children.

And to make matters worse, many of these students — after graduating from an American high school — struggle to find a job or go to college in the United States, which in turn necessitates a return to Mexico.

“It is a strain on both the students and the teachers,” said Deborah Pace, a retired McAllen, Texas, schoolteacher, about the influx of illegal immigrant children.

Pace was a guest on Fox News’ “The Ingraham Angle” on Thursday night.

Pace added that most of the illegal alien children entering the school system in McAllen do not speak English.

In addition, many are illiterate in their native language, as they come from poor countries where a good education is not available to them.

When non-English-speaking illegal alien students enroll in an American public school, they receive instruction in English for part of the school day.

The rest of the day is spent in the regular classroom setting, where teachers are presenting lessons in English — the bulk of which the non-English-speaking students cannot understand, Pace explained.

“A lot of them sometimes go back to Mexico because their options are limited.”

“A lot of these students do come in. They work hard. They learn the language. They pass. They get a diploma, and then what?”

“They realize that without a Social Security number, they cannot get a job,” Pace said.

“It’s difficult to go to college,” Pace also explained — since these students are eligible only for state financial aid, not federal.

President Donald Trump visited with border agents at a patrol station on the U.S.–Mexico border in McAllen on Thursday as lawmakers back in Washington, D.C., remain deadlocked over funding for the president’s proposed wall and ending the partial government shutdown.
