(CNN)After a difficult, monthlong journey from Central America to the US-Mexico border, dozens of asylum-seeking migrants are vowing to remain outside an immigration processing center until "every last one" is admitted into the country, an organizer with the caravan said late Sunday.
Earlier, the migrants marched from Friendship Park in Tijuana, Mexico to the San Ysidro port of entry. They stood on the Mexican side; on the other side lay San Diego, California. It was the final leg for some in the caravan of hundreds of migrants, which had reached Tijuana on Tuesday.
Alex Mensing, an organizer with Pueblo Sin Fronteras, which assembled the caravan, said 50 migrants were admitted to the immigration processing center. He said the migrants' decision to not return to a nearby shelter overnight was made in solidarity with the asylum seekers who are inside the facility.
But the migrants' fate is uncertain. Before the group arrived, US Customs and Border Patrol officials said the port had already reached full capacity, and migrants trying to get into the United States may need to wait in Mexico as officials process those already in the facility.
