A record number of migrant arrivals reported along the U.S.-Mexico border in fiscal year 2022 surpassed 2 million in August, an all-time high. The phenomenon was driven in part by unprecedented levels of migration from Cuba, Venezuela and Nicaragua, according to government data.
With Mexico agreeing to work with the U.S. to create smart border technology, the future of what the border might look like is up in the air.
Currently, America's "border wall" is a series of piecemeal barriers that vary in size, shape and age. Sections of "wall" include low fences, high barriers, dividers with steel slats and areas with checkpoints and pedestrian passages. Other parts of the border have no structures at all, demarcated instead by rivers or mountains.
Here's what the U.S.-Mexico border really looks like — both the areas with walls and without.
A border tunnel under the wall
On May 16, 2022, an underground tunnel the length of a football field was discovered under the border wall between Tijuana and San Diego.
Homeland Security Investigations provided this photo to the Associated Press. This tunnel was under one of the most fortified parts of the border wall.
Planting flowers at the beach
This is the end of the border wall on the West Coast in Tijuana, Mexico. The barrier extends all the way out into the Pacific Ocean.
Here, a woman plants flowers on the beach as the sun sets on the Mexican side of the border on April 7, 2022.
Displaced Ukrainians seeking asylum
When Ukraine was attacked by Russia in early 2022, many Ukrainian refugees fled to Mexico to seek asylum at the U.S. border.
U.S. authorities opened the El Chaparral port of entry outside of Tijuana, Mexico, in April 2022 to allow for the processing of Ukrainian refugees specifically. Their humanitarian parole lasts one year.
Texas Army National Guard member on patrol
A member of the Texas Army National Guard is on duty at an opening in the border wall.
In September 2021, thousands of migrants, mostly refugees from Haiti, made camp at a makeshift migrant encampment under a nearby bridge in Del Rio, Texas,, causing U.S. Customs and Border Protection to temporarily close the port of entry there and instead focus more on border patrol.
Unfinished border wall
This unfinished section of the U.S.-Mexico border wall in La Joya, Texas, sits in the blazing summer heat in July 2021.
Texas Governor Greg Abbott has pledged to use state funding for the completion of the border wall across the state.
Reuniting on the border
A man embraces a female relative in Ciudad Juarez, Mexico, on June 19, 2021.
The event is part of an annual event that takes place across the Rio Grande called "Hugs Not Walls" in which U.S. migrants are allowed to reunite with their family members on the other side of the border for a few minutes, regardless of their immigration status or circumstances.
National Guard members patrol unfinished sections of the border wall
Unfinished sections of the border wall, such as this one in La Joya, Texas, are often heavily guarded by members of the U.S. National Guard or border control agencies.
In late 2021, migrant border crossing rates fell a bit — only to rise again in 2022.
Two people crossing into the United States
Plans to build two walls along the Tijuana-San Diego border have been underway for several years.
In this August 2021 photo, two people from Mexico cross into the United States at an entry point where both the primary and secondary walls were under construction.
Visitors allowed once again
Migrants aren't the only ones who cross the U.S.-Mexico border. Visitors between the two countries do too.
In this photo, U.S. customs agents at the San Ysidro port of entry check visitors' vaccination cards on November 8, 2021, after the border was reopened to non-essential visitors, all thanks to eased COVID restrictions.
Parents-to-be cross gap in border wall
Haitian migrants, including a pregnant woman and her partner, traveled from South America to reach the United States at the border in Yuma, Arizona, in December 2021.
Yuma saw an increase in migrant crossings that month as many tried to reach U.S. soil before a court ordered the re-implementation of a Trump administration policy that compelled asylum-seekers to stay in Mexico during their immigration court process.
Building a second border
A construction site set up here along the San Diego Sector, where a physical border separates the United States and Mexico, is intended to build a second wall alongside the already-existing border wall in 2019.
This secondary wall was part of President Donald Trump's "Build the Wall" campaign promise and was meant to be stronger and more effective.
A construction crew works on a fallen section of the U.S.-Mexico border wall on January 29, 2020. Newly installed pieces of the wall in Calexico, California, toppled in high winds, landing on trees on the Mexican side of the border.

Protest in paint

Berlin Wall section at U.S. border
A portion of the Berlin wall sits in front of the United States-Mexico border wall on November 16, 2019 in San Ysidro, California. The 2.7 ton wall section, which features a letter to Donald Trump, was originally sent to the White House and was rejected and was brought to the U.S-Mexico border by Initiative Offene Gesellschaft, a group dedicated to promoting ideas for an open society.

When the river is the border
Mexican National Guard members prevent a Central American woman and a young girl from crossing the Rio Bravo border into the United States on June 21, 2019. In this area, there is no wall; the river acts as a border and, often, a deterrent.
Back to Mexico
The woman and girl were detained by members of Mexican National Guard in Ciudad Juarez.

Asylum restrictions take effect
Migrants seeking asylum in the United States are assigned a number at the Civil Registration Office in Ciudad Juarez, Mexico. This sign indicates that the last number to enter is 12,552.
On September 11, 2019, the U.S. Supreme Court allowed asylum restrictions imposed by the Trump administration to take effect, preventing most Central American migrants from applying at the U.S. border.
On the U.S. side of the fence, a boy holds a sign during a prayer with priests and bishops from both Mexico and the United States. This section of the fence, on the outskirts of Ciudad Juarez, was one of the first to be constructed.

A self-appointed militia
Jeff Allen and Jim Benvie, plus two men identifying themselves only as Viper and Stinger, share cigarettes while patrolling the U.S.-Mexico border in Sunland Park, New Mexico. These aren't Border Patrol officers; they are a self-appointed militia. Members say they will patrol until a wall is built.
Private citizens patrolling the border
The militia calls itself United Constitutional Patriots New Mexico Border Ops.
Do not enter
