According to a CBP spokesperson, port capacity at San Ysidro is dependent on holding space, volume of traffic, officer resources and complexity of cases among other factors.
“CBP is committed to maintaining security and meeting the health and safety needs of those persons in our custody, the traveling public, and officers and personnel. At times, this has required us to limit the number of people we can bring in the port facility for processing at a given time, including in 2016 when an influx of Haitians arrived at the California border, and as recently as within the past six months. In recent days, San Ysidro has exceeded port capacity due to an increase in arrivals of undocumented persons making asylum claims or presenting complex cases. Accordingly, CBP has had to limit the number of new arrivals for processing. CBP will continue to work with its interagency partners at ICE to ensure continued management of persons presenting without documents and appropriate care and custody of all those in our facility,” the spokesperson said in part.
