The Obama administration is admitting hundreds of African immigrants to the U.S. under a "secret accord" that channels them through South America and Mexico, charges the Washington watchdog Judicial Watch.

"The Obama administration has done a great job of promoting its various back-door amnesty programs, which include perpetually extending a humanitarian measure designed to temporarily shield illegal immigrants from deportation during emergencies," the Judicial Watch report said.

"It's known as Temporary Protected Status (TPS) and in the last few years migrants from several African countries have received it so the new influx is not all surprising."

The Obama administration already has opened the door to thousands of young men from Syria, designated them as refugees "refugees." It also tried to grant amnesty to up to 5 million illegal aliens until the plan was slapped down by a federal judge in a ruling the U.S. Supreme Court let stand.

The new discovery by Judicial Watch said African immigrants "are being housed in shelters in the Mexican border town of Tijuana while they await entry into the United States under what appears to be a secret accord between the Obama administration, Mexico and the Central American countries the Africans transited on their journey north."

The report cited an article in a Mexican newspaper that said Mexico's immigration regulators, the Instituto Nacinal de Migracion, said Mexico is "living through a wave of undocumented Africans, due to a humanitarian crisis on that continent, that has saturated shelters in Tapachula, Chiapas, and generated pressure on shelters in Tijuana, Baja California."

The Africans are granted special status by Obama because of issues such as the 2014 Ebola epidemic. Mexican officials say the backlog is aggravated by the "slow pace" of U.S. immigration officials in San Isidro, who process only 50 asylum applications daily.

The journey for the migrants begins by traveling to Brazil "under a South American policy that allows the 'free transit' of immigrants."

Judicial Watch said Ecuador, Costa Rica, Nicaragua and Panama "facilitate the process by transferring the concentration of foreigners towards Mexico based on an agreement that Mexico will help them gain entry into the U.S. so they can solicit asylum."

The Washington watchdog said the Africans mostly enter Mexico through Chiapas, which borders Guatemala.

"This week alone 424 Africans arrived at the Chiapas immigration station, which is situated in Tapachula. Shelters in Tijuana currently have 154 migrants from African countries waiting on their U.S. asylum solicitations, according to figures provided by the INM," Judicial Watch said.

The Mexican newspaper report said they don't want to stay in Mexico.

Tijuana officials have reported helping migrants from Somalia, Ghana and Pakistan get into the U.S. through San Isidro.

The special access status for Somalians was just extended by DHS Secretary Jeh Johnson until March, 2017.

The Obama administration cited the conditions in Somalia for providing the special treatment.

"There continues to be a substantial, but temporary, disruption of living conditions in Somalia due to ongoing armed conflict that would pose a serious threat to the personal safety of returning Somali nationals, as well as extraordinary and temporary conditions in the country that prevent Somali nationals from returning to Somalia in safety," said a notice in the Federal Register.

"The secretary has also determined that permitting eligible Somali nationals to remain temporarily in the United States is not contrary to the national interest of the United States."
