Over recent years, migrants have set up camp in Matamoros awaiting entry to the US. Immigrant advocates called the situation a humanitarian crisis just feet from the US southern border that formed as a result of harsh Trump administration policies.
President Joe Biden ended the Trump-era policy, informally known as "remain in Mexico," and kicked off the process of allowing entry to migrants who had been subject to it. The camp in Matamoros is one of many locations where migrants had been forced to stay and had become emblematic of the "remain in Mexico" policy.
DHS said Saturday the Biden administration, in partnership with international organizations, have completed registration of individuals staying at the camp.
