Hundreds of thousands of migrants lost scheduled appointments after CBP One app was disabled, creating uncertainty at the US-Mexico border.

The initial blow came with the end of CBP One, stranding thousands of asylum seekers with and without appointments

President Trump took action to close the nation’s southern border and terminate a widely used app. Many migrants expressed despair, and some moved to cross the border anyway.

CBP One has been wildly popular, especially with Venezuelans, Cubans, Haitians and Mexicans. Now, they were stranded at the U.S. border or deeper in Mexico.

Dozens of migrants wait in Tijuana for information regarding their migration appointments as US President Donald Trump ends the use of a border app called CBP One, which has allowed people to legally enter the United States to work.

Migrant shelters in Tijuana — located across the border from San Diego, California — are bracing for a possible surge in the influx of migrants should US President Donald Trump carry out his mass deportation plan.

The president moved quickly to cancel the CBP One app, which allowed migrants to schedule appointments to gain entry into the United States, turning away potentially tens of thousands of migrants.

Mexico will give humanitarian aid to migrants from other countries whose asylum appointments were cancelled, as well as those sent to wait in her nation under the revived policy known as Remain in

"I believe, especially in in our border, in Tijuana and San Diego will see a lot of suffering," said Professor Rafael Fernández de Castro.

During the inauguration of Donald Trump as the 47th President of the United States, the CBP One mobile application, a tool used by thousands of migrants to schedule appointments at the border, ceased to be operational.

Hours after the Pentagon announced that it would send 1,500 active duty troops to the U.S.-Mexico, reports surfaced that the number was actually 10,000.
