Mexico's Immigration Control Efforts

Background
Migration issues continue to be a high priority for U.S.
policy and Congress, particularly as U.S. Customs and
Border Protection (CBP) has reported record numbers of
migrant encounters on the Southwest border. Mexico, like
the United States, has struggled to deal with large numbers
of migrants, especially families and unaccompanied minors,
many of whom seek asylum. Mexican President Andres
Manuel L6pez Obrador has accommodated U.S. policies
that have shifted some of the burden of interdicting
migrants and hosting asylum seekers from the United States
to Mexico. It is unclear, however, how Mexico will respond
to any further changes in U.S. asylum policies that may
affect Mexico.
Increases in U.S.-bound migration through Mexico have
strained Mexican government resources and placed
migrants at risk of harm. Historically, migrants entering
Mexico have emigrated mostly from the Northern Triangle
countries of Central America (El Salvador, Guatemala, and
Honduras). Since the Coronavirus Disease 2019 pandemic,
the number of migrants entering Mexico from regions
beyond Central America has increased substantially. In
2022, for the first time, Mexican authorities apprehended
more migrants from the Caribbean and South America than
from the Northern Triangle (see Figure 1).

Mexk     s Immigration Control Policies
Since 2014, with support from the United States, Mexico
has established naval bases on its rivers, security cordons
north of its borders with Guatemala and Belize, and drone
surveillance in border regions. Unarmed agents from the
National Migration Institute (INM) have increased
operations along train routes and at bus stations, improved
infrastructure at border crossings, and set up mobile
highway checkpoints. The agency reportedly conducts

biometric screening of migrants at detention centers using
equipment supplied by the U.S. Department of Homeland
Security (DHS). INM also has sought to professionalize its
workforce and to improve coordination with customs and
federal, state, and local security forces. Despite reform
efforts, INM retains a reputation for corruption and weak
observance of migrant protections. As a result, migrants
remain vulnerable to crime and other abuses.
In 2018, President L6pez Obrador took office pledging to
adopt a humanitarian approach to migration and to promote
development in Central America as a solution to
unauthorized migration. The government's record in these
areas is mixed. For example, the Commission for the Aid of
Refugees (COMAR) has remained underfunded and retains
a large backlog of asylum cases. Observers also have
questioned the effectiveness of Mexico's contribution to
Sembrando Oportunidades (Sowing Opportunities), a U.S.-
Mexico development program to address the root causes of
irregular migration from the Northern Triangle.
Since 2019, L6pez Obrador has taken a harder line toward
migration, in part due to U.S. pressure. His government has
increased migrant apprehensions and restricted access to
humanitarian visas, particularly for those traveling in large
groups (caravans). As during prior enforcement surges,
migrants have taken more dangerous routes and increased
their reliance on smugglers. After Mexico deployed its new
National Guard for migration enforcement, reports of
mistreatment of migrants rose. In a January 2021 operation
against migrant smugglers, state police reportedly killed 19
people, including Guatemalan migrants, near the U.S.
border. Since 2021, Mexico has sought to keep asylum
seekers in southern Mexico despite dire conditions there.
Mexico also has enforced new visa requirements for those
from Brazil, Ecuador, and Venezuela, and increased
expulsions.
Humanitarian Protecton jn Mexico
Mexico has a broader definition of refugee than the United
States and the 1951 U.N. Refugee Convention; Mexico
recognizes a right to asylum based on generalized
violence; foreign aggression; internal conflicts; massive
violations of human rights; and other circumstances leading
to a serious disturbance of public order. As a result, many
of the migrants arriving in Mexico from the Northern
Triangle and elsewhere could qualify as refugees under
Mexican law.
Asylum requests tripled in Mexico from 2017 to 2019,
declined in 2020 due to the pandemic, and have surged
since 2021 (Figure 2). With support from the U.N. High
Commissioner for Refugees (UNHCR), COMAR reduced
the asylum request backlog in 2020 before again struggling
to meet record demand in 2021. In 2022, Mexico received
