The first flight carrying third-country nationals from the U.S. has arrived in Jamaica. This marks the start of a controversial agreement using Jamaica as a transit hub for migrants. The Supreme Court will debate the legality of such agreements, which have increased since the Trump administration. On Tuesday, 22 migrants arrived in Kingston and were taken to an undisclosed location. Jamaican authorities emphasize the arrangement is safe and lawful. The agreement, signed in June, allows non-Jamaican migrants to transit through Jamaica before reaching their home countries. Critics argue the Jamaican Parliament was bypassed, raising transparency concerns.
