They just keep coming.

A report from the Center for Immigration Studies indicates another 35,000 African migrants are on their way to the United States.

According to CIS’s Todd Bensman:

Like the proverbial “bulge in the belly of the snake,” unusually high numbers of non-Latino migrants, obviously not from Central America, are now reportedly passing from Colombia through Panama on their way to the U.S. southern border. Their numbers range to the tens of thousands, whose vanguards we have already seen at the U.S. Southwest Border in recent months: Cameroonians, Ghanaians, Congolese, Haitians, Cubans, and some from the Middle East.

Word of their successful entries into the United States this year clearly reached home countries because now a swell numbering as many as 35,000 is on an infamous migrant passage through which migrants have long funneled from South America to North America: the Darien Gap.

I am told this by two eye-witnesses who have just returned from the Colombia-Panama region on either side of the Gap. One of them is Panama-based author and freelance journalist Chuck Holton, who just visited the Colombian side in the frontier border town of Turbo, which is notorious as a migrant staging area for U.S.-bound migrants to be smuggled through the Darien Gap passage into Panama. The other source is Diane Edrington, a Mississippi-based nurse practitioner who has worked for years as a Panama Missions volunteer and who just returned from camps I visited in December on the Panama side of the Darien Gap.

Holton tells Bensman the word is out on US sanctuary cities.

“They have some level of understanding of what a sanctuary city is. ‘If we can get to one of those they won’t mess with us; They won’t get us out,'” he says, according to the CIS report.

“A lot of these guys obviously do not qualify for asylum,” Holton says. “When they talk to me, they don’t have a problem telling me it’s for economic benefits, to get a better job, to have a better life.”

The report comes on the heels of waves of Africans coming to the US via Mexico.

The Epoch Times’ Charlotte Cuthbertson was in Tapachula, Mexico on Friday and filmed a mob of Haitians trying to get visas to pass through the country to get to the United States.

“A lot of these migrants are from Haiti and Africa,” Cuthbertson narrates.

“And we just talked to someone who works in the facility and he said, about on average, 1,500 more people come in each day and about 500 go out,” she said.

Cuthbertson said the center is getting “pretty swamped.”

She says she talked to some of the Haitian migrants who had moved to Venezuela, but due to terrible conditions there, they’re now US-bound.

“Everyone’s goal is to come to the US,” Cuthbertson said.

Video released by Customs and Border Protection shows Africans and Haitians crossing the Rio Grande River and strolling into America. The agency has since deleted the video.

Many migrants could be seen arriving in designer clothes, toting luggage and backpacks with their kids in tow.

“#USBP Del Rio Sector Border Patrol agents apprehended 2 large groups of over 100 in 2 days,” CBP South Texas wrote in a video post on Twitter. “Total of 3 large groups this fiscal year.”
