Vladi was just 15 years old when he joined a migrant caravan, travelling all the way from El Salvador, to Tijuana on the US-Mexico border. He arrived there last autumn with his grandmother. But by November, Vladi, was on his own. His grandmother needed to return to El Salvador, and Vladi remained at a youth shelter for other unaccompanied migrants like him. Many were hoping to seek asylum in the United States. So was Vladi. But ahead of them is the hostility of the Trump administration. The story of one family in America’s migrant crisis.
