FOX NEWS - The hundreds of asylum-seekers who traveled through Mexico toward the U.S. approached the San Diego border crossing Sunday -- but officials have signaled they may not be able to make it through.
"At this time, we have reached capacity at the San Ysidro port of entry for CBP (Customs and Border Protection) officers to be able to bring additional persons traveling without appropriate entry documentation into the port of entry for processing," Commissioner Kevin McAleenan told Fox News in a statement.
He said the immigrants "may need to wait in Mexico as CBP officers work to process those already within our facilities."
Immigration officials had warned that the San Ysidro border crossing may not be able hold many asylum-seekers if it faces too many at once. The port of entry, according to the agency, can hold about 300 people temporarily.
Roughly 200 people, including women and young children, were expected to turn themselves over to border inspectors after arriving in Tijuana last week, claiming they had a credible fear of persecution at home. Demonstrators gathered along the border to hold a rally in the hours before crossing over, with some people scaling the fence.
"The only thing I would tell Mr. Trump is to have a conscious and to look at all the people and the way they suffer. Because the people, they are coming from those countries, they are not doing it for pleasure," Osman Salvador Ulla Castro, who is from Honduras, told Fox News. "They face danger and extortions and they are looking for a better life."
