On the US border, the scene repeats itself several times a day: individuals, and families crossing the Rio Grande from the Mexican city of Piedras Negras into Eagle Pass, Texas. Every year, thousands of migrants seeking a better future undertake the dangerous journey. "I'm crying (...) I'm so happy," Alejandro Galindez, who left Venezuela and got to Texas 26 days later, tells AFPTV. In Eagle Pass, Valeria Wheeler, the director of the shelter Mission Border Hope, witnesses every day the challenges of the wave of migration. In two years, her facilities have gone from taking in between 20 migrants a week to up to 600 a day. "They come physically injured (...) in addition to emotional wound," Wheeler explains.
