Immigrant advocates plan to challenge a new Trump administration rule that would force migrants headed toward the Southern border to apply for asylum in the first country they pass through.

The Trump administration announces a new step in its efforts to turn back asylum-seekers crossing the U.S.-Mexico border. Those seeking asylum would have to do so in the first country they enter.

President Trump says immigration raids are planned for Sunday in cities across the country. The administration is reported to be targeting a few thousand unauthorized immigrants.

When DHS officials started sending migrants back to Mexico to wait for immigration court, they said that "vulnerable" populations could be excluded. But in practice, that's not always happening.

Immigrant communities are once again bracing for nationwide raids targeting migrant families that are expected to begin Sunday.

About 104,000 migrants were taken into custody after crossing the Southwest border — a 28% drop from May. The hot-weather drop "outpaces last year's decline by 11 percent," DHS said.

Immigrant advocates are outraged that ICE is using driver's license photos without consent. But it's not the first time U.S. authorities have pushed the envelope to enforce immigration laws.

Federal officials are expected to announce this week that the number of migrants crossing the Southern border has declined after months of increases.

Among the migrants arriving at the U.S.-Mexico border are extended family members with children in tow, hoping to give them a better life. But many of them may never join those children in the U.S.

The inspector general's office visited Customs and Border Protection sites across the Rio Grande Valley in South Texas. They found migrants penned in overcrowded Border Patrol facilities.

The "Remain in Mexico" program is a key part of the Trump administration's plan to turn back a crush of migrants at the southern border, and it's a historic shift in how the asylum system works.

Advocates described desperate and squalid scenes in detention facilities. Days later, reporters given a tour of a Border Patrol station at Clint, Texas, saw a clean, orderly facility.

The Trump administration's new migration policy "Remain in Mexico" requires asylum seekers to wait in Mexico for their day in U.S. immigration court. But many migrants are confused and scared.

Advocates say migrant children face a public health emergency because of the conditions where they are being held. Federal officials pushed back by taking reporters on a tour of a West Texas Center.

On Wednesday, Border Patrol officials took reporters on a tour of a facility in Clint, Texas, where a group of lawyers allege children were detained without adequate food, supplies and sanitation.

As Congress moves forward with a $4.5 billion humanitarian aid bill to address the border crisis, migrants still arrive each day. But U.S. policy is beginning to shift the crisis to the Mexican side.

President Trump chose Orlando, Fla., for the official kickoff of his reelection campaign. Also, he tweeted about an intensified immigration enforcement effort.

President Trump threatened to deport "millions" of immigrants living in the U.S. illegally. Immigration and Customs Enforcement will begin the process as soon as "next week."

The administration named high-profile immigration hawk Ken Cuccinelli to lead the agency in charge of citizenship and visas, raising concerns among immigrant rights advocates.

Those working on behalf of immigrants say wait times for green cards and visas are reaching crisis levels. And with a leadership change at the agency in charge, the wait could get even longer.
