Here’s what the scaremongers think they know about sequestration and immigration: that hundreds of undocumented criminal aliens will be let loose and hundreds more will swarm through our unsecured borders, steal American jobs, and abuse our welfare system. Setting aside the facts that many being released from detention are guilty of only minor infractions, that net migration from Mexico is practically nonexistent, and that immigrants give more than they take, the vast majority of immigrants in the United States are legal permanent residents or naturalized citizens. These nearly 30 million people will certainly be set back by meat cleaver–like sequestration cuts. And that should be of concern to all of us.

One federal program for which immigrants are eligible is Head Start, which offers competitive grants for comprehensive early childhood services for low-income children and families. Under sequestration, Head Start funds will be cut by as much as $622 million, which translates to over 96,000 fewer children served.

The automatic cuts to education, however, will have ripple effects throughout the economy. Children of immigrants are the fastest-growing segment of the U.S. population. According to an Urban Institute study, they account for nearly the entire growth in the country’s child population during the past two decades. As of 2010, one in four children in the United States lives in an immigrant family.

This considerable demographic shift will have major social, political, and economic implications for the country. In less than a decade, today’s immigrant children will make up a large proportion of new workers, taxpayers, and voters who will bear the responsibility of supporting aging baby boomers. It is crucial, then, to provide quality education for these children.

A functional and successful public education system can help secure economic and social parity for immigrant children and their families by giving students a solid foundation for higher education and subsequent gainful employment. This in turn can promote intergenerational mobility for immigrant groups. Ultimately, better mobility means a more productive economy and much-needed revenue for the government.

Poorly funded public schools can widen existing economic and social gaps between racial and ethnic groups and between haves and have-nots by denying disadvantaged students the educational foundation they need to progress. Educating immigrant children, however, is and will be daunting for public schools due to the schools’ diminished capacities and increased accountability burdens coupled with the linguistic and cultural challenges unique to immigrant students.

English proficiency is a significant barrier. Two in five immigrant children are English language learners, and three in four live in households where no one older than 13 speaks English proficiently. In addition, many immigrants have limited financial resources. Children in immigrant families make up close to a third of the nation’s poor children and a similar proportion of the nation’s low-income children. Five in ten immigrant children live in low-income families, compared with four in ten native-born children.

This tenuous situation will be exacerbated by cuts in discretionary spending for federal education programs. Title I grants to local education agencies—a cornerstone program designed to help all students, especially those from disadvantaged backgrounds, meet high academic standards—are to be slashed by a whopping $1.1 billion. This will leave 1.8 million fewer students served, among whom are hundreds of thousands of immigrant children. English language acquisition state grants, which help English language learners and recent immigrant students learn English and become proficient in academic content standards, are to be cut by over $57 million, resulting in over 350,000 fewer immigrant students assisted.

Coupled with state budget shortfalls (which can only worsen when the federal cuts kick in), sequestration will set immigrant children and their families further back. If so much of our future workforce falls behind now, all of us will face the consequences in the not-too-distant future.
