Yasaman crossed more than half a dozen countries on foot, bus, and boat and paid thousands of dollars to smugglers to reach Mexico.
Yasaman, an Afghan woman whose name has been changed to protect her identity, believed she was within touching distance of realizing her dream: entering the United States.
But her hopes came crashing down on January 20, when new U.S. President Donald Trump declared an emergency on the southern border with Mexico as part of a crackdown on illegal immigration.
As part of the executive order, U.S. authorities shut down the CBP One mobile app -- the only legal way for migrants to make an appointment with U.S. Customs and Border Protection officers, request asylum, and enter the country legally.
"I don't know what to do now," said Yasaman, who arrived in Mexico in November 2024. "I'm waiting [for] what Trump will decide next about migrants."
Yasaman, speaking by telephone from Mexico, said she received a notification on January 20 that read: "Existing appointments scheduled through CBP One are no longer valid."
The shutdown of the app will affect thousands of migrants, including Afghans, hoping to enter the United States legally.
Around 1 million appointments had been scheduled through CBP One since it was introduced in January 2023.
Not Happy In Brazil
Mexico has been a relatively new route for thousands of Afghan migrants seeking a new, better life in the United States.
RFE/RL contacted the United Nations refugee agency and the Mexican migration authorities to find out how many U.S.-bound Afghan migrants are currently in Mexico. We have not received a response.

Karimullah, whose name has been changed over privacy concerns, said Afghan migrants live in rented apartments, relying on the "limited amount of money" they have brought from Afghanistan or borrow from their relatives abroad.
"Families go hungry for days while waiting for money from relatives," he said.
A former civil rights activist, Karimullah fled Afghanistan after the hard-line Taliban returned to power in August 2021.
Yasaman works as a kitchen helper at a restaurant in Mexico City.
After running out of money to pay for food and rent and as she was still waiting to get an appointment through CBP One, Yasaman got a job as a kitchen helper at a restaurant in the capital, Mexico City.
Like many other Afghan migrants in Mexico, both Karimullah and Yasaman had already been offered asylum in other safe countries -- in their case Brazil, which has issued thousands of humanitarian visas for Afghan nationals since 2021.
Asked by RFE/RL why they didn't want to stay in Brazil, where they had been given free accommodation and food, both Karimullah and Yasaman said they did not see a "good future" there due to a lack of jobs and other opportunities.
Instead, many Afghans pay money to people-smugglers to take them through Bolivia, Peru, Equador, Colombia, Panama, and other countries to reach the U.S.-Mexico border.
'Life For Immigrants Not What It Used To Be'
Some cross the border illegally. Ehsan Khan, a 26-year-old former driver from Kabul, entered the United States illegally in November 2024, hoping to get settled in the country before Trump closes the U.S. borders.
After spending two months at an immigration detention facility, Khan was released on January 11 with an electronic ankle bracelet for authorities to monitor his movements.

Khan did not give details of his new life in the United States but said it isn't worth the traumatic journey he had through Honduras and Guatemala, where he said he "was beaten by thieves who demanded money" and witnessed his best friend drown in the sea.
"I saw my friend screaming for help as he drowned and I looked helplessly. I wanted to jump into the water, but I knew I couldn't swim. His parents often call me from Kabul and ask about him, and we cry," Khan said.
Back in Mexico City, Yasaman is determined to enter the United States "by any means, legally or illegally."
"I don't have a life or home in Afghanistan to go back to," Yasaman said. "I see my future only in America."
