(nyt) SAN PEDRO DE MACORIS, Dominican Republic — Two obsessions define this country: baseball and Haiti. Ángel Luis Joseph, a teenage outfielder with a hot bat, is caught between Dominicans’ devotion to the one and disdain for the other. So many major leaguers have emerged from this sugar town that agents keep an eye on even pint-size players with potential. Ángel, 17, was only a lanky grade school boy when his coach noticed he showed all the signs of becoming a standout. Before long, the San Francisco Giants came calling with a 0,000 offer, he said. But then politics interfered with his dream. To obtain a visa to the United States, Ángel went to a local government office to get a copy of his birth certificate. Little did he know that the Dominican government had recently begun a crackdown on the children of Haitian immigrants, even those like him who have lived their whole lives in the Dominican Republic. “If your last name is weird, they won’t give you your documents,” he said. “Same thing if your skin is dark like mine.” Ángel’s request for his birth record was denied, prompting the Giants to withdraw the offer. His parents, like hundreds of thousands of others, moved from Haiti to the Dominican Republic in the 1970s to work in the sugar cane fields. Their children were born in the Dominican Republic, grew up here and became, in their eyes at least, full-fledged Dominicans. They speak Spanish, dance merengue and play “pelota,” the popular name for the Dominican pastime baseball. “They don’t play baseball in Haiti,” said Melanie Teff, who has studied the issue for Refugees International, an advocacy group in Washington. “That shows how Dominican this guy and many people like him are.” The government does not necessarily agree, and Ángel awaits a ruling on his appeal for access to his Dominican birth record. The issue arose with a fury several years ago when advocates took the government to the Inter-American Court of Human Rights, whose jurisdiction the Dominican Republic acknowledges, to protest the denial of birth certificates to two ethnic Haitian children. While the case was in process, the government changed its migration law in 2004 to specifically exclude the offspring of Haitian migrants from citizenship. The Dominican Constitution grants citizenship to those born on Dominican soil, except the children of diplomats and those “in transit.”
