The overall percentage of lawful immigrants to the United States choosing to apply for and gaining citizenship is at its highest level in more than two decades. Yet in terms of naturalization rate, Mexicans – the single largest group of lawful immigrants by country of origin – lag well behind green-card holders eligible to apply from other parts of the globe.

Based on Pew Research Center estimates using the most recent U.S. Census Bureau data available, two-thirds (67%) of lawful immigrants eligible to apply for U.S. citizenship had applied for and obtained citizenship by 2015. This is the highest share since at least the mid-1990s. But among Mexican lawful immigrants eligible to apply, only 42% had applied for and obtained U.S. citizenship by 2015, a rate little changed since 2005 and one of the lowest among all immigrant groups when it comes to country of origin.

Naturalization rate

The number of naturalized immigrants divided by the number of naturalized immigrants plus the number of lawful immigrants who are eligible to apply for naturalization in a given year.

As part of a larger survey of Hispanic immigrants fielded in late 2015, Pew Research Center asked Mexican green-card holders why they had not yet become naturalized U.S. citizens. The most frequent reasons centered on inadequate English skills, lack of time or initiative, and the cost of the U.S. citizenship application. These appear to be significant barriers, as nearly all lawful immigrants from Mexico said they would like to become U.S. citizens someday.

Overall, 11.9 million of the nation’s 45 million immigrants in 2015 held lawful permanent residence (LPR) status – that is, they held “green cards,” according to Pew Research Center estimates. Of this number, most (9.3 million) had met the eligibility requirements – including length of residence – to apply for U.S. citizenship in 2015.1 Mexicans made up 37% of this group and constituted the single largest group of green-card holders without U.S. citizenship by country of origin.2

In the United States, the citizenship, or naturalization, rate among all lawful immigrants steadily increased from 1995 to 2005, rising from 47% to 62%. Until about 2005, the naturalization rate among lawful immigrants from Mexico also increased steadily, but did so more rapidly (from 20% in 1995 to 38% in 2005), narrowing the gap between Mexicans and other immigrants. However, between 2005 and 2010, the naturalization rate of Mexican green-card holders leveled off, even as the rate for lawful permanent residents from other parts of the globe continued to rise. Only in the period from 2011 to 2015 did the rate of naturalization among eligible Mexican immigrants significantly increase again at a pace higher than that of other lawful U.S. immigrants – going from 38% to 42% among Mexicans, compared with a 2-percentage-point increase, from 72% to 74% among non-Mexican immigrants.

As of 2015, the naturalization rate for lawful Mexican immigrants trailed that of green-card holders from the Middle East by 42 percentage points (42% vs. 83%), and was 33 points behind green-card holders from Africa, 74% of whom had naturalized by 2015. Middle Eastern immigrants had the highest naturalization rate among all immigrant origin groups, while African immigrants saw the highest increase in naturalization rate in the last decade.

Early signs are that 2017 could see an increase in the rate of naturalization of lawful permanent residents. According to the latest figures released by the U.S. Department of Homeland Security’s Citizenship and Immigration Services, there were 525,000 naturalization applications submitted during the first half of fiscal year 2017, which started Oct. 1.3 That number is up 21% from the 435,000 applications submitted in the same period of 2016, which already had seen a spike on naturalization applications compared with previous years. The total applications for fiscal 2016 were up by 24% compared with 2015, and represented the highest number of applications for naturalization since 2008. Meanwhile, the number of lawful permanent residents admitted since 2010, many of whom would have recently become eligible to apply for citizenship, has stabilized at around 1 million per year since 2010.

Even so, the volume of citizenship applications in 2017 and 2016 still pales in comparison to the record levels seen in 1997 (1.41 million applications) and 2007 (1.38 million).These spikes were triggered in large part by congressional legislation passed a decade earlier that provided a path to lawful permanent residence and eventual citizenship for many unauthorized immigrants.4 The spike in 2007 occurred ahead of an increase in the citizenship application fee for adults, which rose from $330 to $595 on July 30, 2007.

Some have posited that fiscal 2016’s growth in applications and the more recent spike during the first quarter of fiscal 2017 (right after the election) are attributable to anti-immigrant rhetoric associated with 2016 U.S. presidential election. There is also evidence that some organizations worked to help lawful immigrants submit naturalization applications during the campaign.5 But at least some immigrants may have applied to avoid a further $45 increase in the citizenship application fee that was scheduled to go into effect Dec. 23, 2016. That increase, which raised the total application fee to $640 per adult, was officially announced in May 2016.

Naturalization rates among Mexican and other Latino immigrants

In 2015, half (52%) of all Latino lawful immigrants (mainly originating from Mexico, as well as Central and South America) eligible to become U.S. citizens had in fact naturalized. Among this group, Mexicans had a naturalization rate of 42%, compared with 64% among lawful immigrants from other countries in Latin America.

In its 2015 survey of Latino immigrants, Pew Research Center found that among lawful Mexican immigrants and other Latino immigrants, the desire to become U.S. citizens was high. Nearly all (98%) Mexican lawful immigrants and 94% of other lawful Latino immigrants said they would naturalize if they could.

The survey also found that about two-thirds (67%) of Mexican lawful permanent residents said they had investigated the citizenship application process, compared with 80% of non-Mexican Latino lawful permanent residents. And a large majority of Mexican and other Latino lawful permanent residents (70% and 66% respectively) said they planned to stay in the U.S. and not return to their home country later in life, one reason some of them might seek U.S. citizenship.

Despite their wish to naturalize, many Latino lawful immigrants were not familiar with details of the process. Just 16% of Mexican and 21% of other Latino lawful immigrants correctly answered that two tests are part of the U.S. naturalization process.

It is not only Latino lawful permanent resident immigrants who want to become U.S. citizens:  In the 2015 survey, Latino immigrants who did not have a green card and were not eligible to naturalize (a group likely in the country without authorization) also wanted to become U.S. citizens.6 According to the survey, fully 91% in this group said they would naturalize if they could, and about one-third (32%) had done some research into the steps needed to become a U.S. citizen, though only 5% knew they need to take two tests to naturalize.

 

Mexican and non-Mexican Latino lawful immigrants face somewhat similar barriers to citizenship

Asked why they hadn’t yet naturalized, the Center’s 2015 survey found that 35% of Mexican and 23% of other Latino immigrants with green cards identified personal barriers, such as a lack of English proficiency. Another common reason given was a lack of interest or just having not applied yet. About a third (31%) of Mexican lawful immigrants said this, while only 16% of non-Mexican Latino immigrants said the same. An additional 13% of Mexican and 19% of non-Mexican lawful immigrants identified financial and administrative barriers, mainly the cost of naturalization.

This report is based on three data sources. Data on naturalization trends among lawful immigrants are based on Pew Research Center estimates based on the U.S. Census Bureau’s American Community Survey (ACS) and Current Population Survey (CPS). The ACS is a year-round survey of 3.5 million households conducted by the U.S. Census Bureau. The CPS is a monthly survey of about 55,000 households conducted jointly by the U.S. Bureau of Labor Statistics and the Census Bureau. Each March, the CPS is expanded to produce additional data on the nation’s foreign-born population and other topics. Legal status of immigrants in the ACS and CPS is inferred based on methods described in the Center’s research on unauthorized immigrants in the U.S.

Latino immigrant attitudes about naturalization come from a nationally representative bilingual telephone survey of 1,500 Latino adults, including 795 immigrants. The survey was conducted between Oct. 21 and Nov. 30, 2015. The margin of error for the full sample is plus or minus 3.3 percentage points at the 95% confidence level; for foreign-born Latinos, the margin of error is plus or minus 4.4 percentage points. For a full description of the survey methodology, see the Methodology section at the end of the report.

U.S. Citizenship Eligibility

To become a U.S. citizen, a lawful permanent resident in most cases must:

  • Be at least 18 years old.
  • Have lived in the U.S. continuously for five years.
  • Be able to speak, write, read and understand basic English.
  • Answer questions that demonstrate knowledge of U.S. government and history.
  • Undergo a successful background check.
  • Demonstrate attachment to the principles of the U.S. Constitution.
  • Take the oath of citizenship swearing allegiance to the U.S.

Some of those requirements are waived for certain groups:

  • Spouses of U.S. citizens can naturalize after three years of continuous residence, if the sponsoring spouse has been a U.S. citizen for all three years.
  • Foreign-born minor children become citizens when their parents naturalize.
  • Foreign-born minor children who are adopted by U.S. citizens are eligible for citizenship upon their arrival in the U.S.
  • Military personnel, their spouses and foreign-born minor children are eligible for expedited and overseas citizenship processing with the possibility of having some of the eligibility requirements diminished or waived. Additionally, in the case of death as result of combat while serving in active duty, citizenship may be granted posthumously to the military member and immediate family members.

The filing fees of processing a citizenship request for all applicants were $680 at the time of the Center’s survey in 2015. This included a $595 filing fee and an $85 biometric services fee for processing fingerprints. Starting Dec. 23, 2016, the citizenship application fee rose by $45.

The filing fee could be waived for applicants with family incomes below 150% of the poverty line, if they, their spouse or head of household receives a means-tested benefit, or if the applicant is experiencing a financial hardship that prevents them from paying the fee (such as unexpected medical bills). Starting Dec. 23, 2016 there is also a reduced filing fee of $320 available for naturalization applicants with family incomes between 150% and 200% the poverty line.

 

1. Recent trends in naturalization, 1995-2015

In 2015, 67% of lawful permanent residents eligible to become U.S. citizens had done so, the highest level in two decades and a 20-percentage-point increase since 1995.

The population of naturalized U.S. citizens reached 19.8 million in 2015, a historic high that reflects both an increase in the population of eligible immigrants and an increased likelihood that those who are eligible to apply for citizenship actually do so.

 

 

The total number of lawful immigrants – naturalized U.S. citizens and lawful permanent residents – more than doubled since the 1970s, reaching 31.6 million in 2015. And since 2005, the number of lawful permanent resident admissions7 alone has exceeded 1 million annually, with the exception of 2013.

In 2015, a majority (62%) of all the lawful immigrants living in the country had already become naturalized citizens. The rest – 11.9 million – are green-card holders who could eventually naturalize and become U.S. citizens.

In 2015, naturalized citizens accounted for 44% of the nearly 45 million total immigrants living in the U.S., up from 33% of the 33 million immigrants in 2000. (Total immigrants include naturalized citizens, lawful permanent residents, unauthorized immigrants and temporary lawful residents.) During this period, the share of lawful permanent residents among the foreign-born population shrank from 36% in 2000 to 27% in 2015.

 

 

Mexican lawful immigrants have one of the lowest naturalization rates

Among the 9.3 million immigrants eligible to apply for U.S. citizenship in 2015, 3.5 million were from Mexico. That made Mexican immigrants the single largest origin group among those eligible to naturalize, accounting for more than a third of the group.

The naturalization rate among eligible Mexican immigrants has varied over time. In 1995, 20% of then-eligible-to-naturalize Mexicans had done so, compared with a naturalization rate of 54% among non-Mexican immigrants eligible to naturalize – a gap of 34 percentage points. However, in the late 1990s, the Mexican naturalization rate rose more sharply than it did among non-Mexicans overall. As a result, the gap fell to 27 percentage points in 2000 – a record low. From 2005 to 2010, the Mexican naturalization rate had again grown more slowly than it had for other immigrants. From 2011 to 2015, the rate of naturalization for Mexicans grew faster than it did for other immigrants. By 2015, while the Mexican naturalization rate had risen to 42%, for non-Mexicans it had risen to 74% in the same year, leading to a 32-percentage-point gap.

The lower naturalization rate among Mexican immigrants may be influenced by multiple factors. First, Mexican immigrants may maintain closer ties to Mexico because of its proximity to the U.S. and might return home at some point, which would reduce their interest in applying for citizenship. Second, there are personal and administrative barriers that make applying for citizenship difficult for some immigrants, such as a lack of English proficiency. Only about one-fourth (26%) of Mexican immigrants eligible to naturalize are proficient in English, compared with about half (51%) of lawful immigrants from other countries of origin. Also, the cost of naturalization is a possible barrier for some applicants. Overall, lawful Mexican immigrants have lower family incomes than lawful immigrants of other origins.8 In addition, Mexican immigrants may not be aware that they can hold both U.S. and Mexican citizenship at the same time. (Prior to 1998, Mexico did not allow its citizens to hold dual citizenship, though this has since changed.) A Pew Research Center survey of Mexican immigrants in 2012 showed 29% were not aware this was possible. Also, some lawful immigrants might perceive that citizenship awards few additional benefits to their lawful permanent resident status.

2. Why Mexican lawful immigrants have not naturalized

Despite their very low rate of naturalization, many Mexican lawful immigrant adults who had not yet naturalized said they wanted to do so, according to the 2015 Pew Research Center survey. For example, nearly all (98%) said they would naturalize if they could, and about two-thirds (67%) said they had researched the administrative steps needed to become a U.S. citizen, an indication of their interest in seeking U.S. citizenship. In addition, 70% said they did not intend to return to Mexico and live there later in life, a further indication of the potential interest of Mexican immigrants in applying for U.S. citizenship and staying in the United States.

Even so, these same immigrants cited many reasons for not having applied for U.S. citizenship yet. Among Mexican lawful permanent residents, about a third (35%) said in an open-ended question that the primary reason for not naturalizing was either language or personal barriers. Another 31% said they had either not tried to apply for naturalization yet or were not interested. An additional 13% cited financial or administrative barriers.

Looking more deeply at the reasons Mexican lawful permanent residents gave for not having naturalized, 27% said they needed to learn English (the leading reason among cited language and other personal barriers). Another 18% said they had not applied because they did not have the time to do so (the leading reason among those saying they had not tried to apply or had no interest). And 8% cited the cost of the application as the reason they have not yet naturalized (the leading reason among cited financial and administrative barriers).

In addition, 8% said they either were currently applying for U.S. citizenship or would do so within the next year. And 3% said they were not yet eligible to naturalize.9

The survey also revealed that although a large majority of Mexican green-card holders said they had done research into the steps to become U.S. citizens, only 16% knew how many tests would be required during the application process, suggesting that even though many have explored what it would take to become a U.S. citizen, many still did not fully understand the process.

 

Differences between Mexican and non-Mexican Hispanic lawful permanent residents for not seeking U.S. citizenship

Latino lawful immigrants from countries other than Mexico had a significantly higher rate of naturalization than their Mexican counterparts (62% vs. 42% in 2015). However, in general terms, both groups showed similar levels of motivation to apply for naturalization, and faced similar barriers in their path to U.S. citizenship, according to the Pew Research Center survey.

Among non-Mexican Latino lawful immigrants, 94% said they would naturalize if they could, and 66% said they were planning to stay in the U.S. and not return to their home countries (compared with 98% and 70% among Mexican lawful immigrants).

In addition, non-Mexican lawful Latino immigrants were as likely as Mexican lawful immigrants to have said they had researched the steps to become a U.S. citizen (80% of non-Mexican vs. 67% of Mexican lawful immigrants). However, only 21% Latino green-card holders of other origins correctly said that they needed to take two tests to gain U.S. citizenship, similar to the share among Mexican lawful immigrants (16%).

In terms of specific barriers to naturalization, Hispanic lawful permanent residents of non-Mexican origin and those of Mexican origin cited somewhat similar reasons for not naturalizing. Mexican lawful immigrants were as likely as their non-Mexican Hispanic counterparts to have said that language and other personal reasons were the main barriers for them to become naturalized U.S. citizens (35% vs. 23%, respectively). By contrast, Mexican green-card holders were significantly more likely than non-Mexican Hispanics to show a lack of interest or said they had not had time to take steps to naturalize (31% vs. 16%).

Not being eligible yet for naturalization or waiting for their green card was the main reason for 22% of non-Mexican Latino lawful permanent residents, while only 3% of Mexican LPRs said this.10 Also, financial and administrative issues were just as important to non-Mexican Latino lawful permanent residents (19%) as to Mexican lawful permanent residents (13%).
