In this Aug. 3, 2015 photo, a post marks the border between Haiti and the Dominican Republic where a footbridge connects the Haitian town of Anse-a-Pitres, top, and the Dominican town of Perdernales. After the D.R.’s June 17 deadline to apply for legal residency under a new program to organize the flow of migrants across the border from Haiti, more than 288,000 people applied. So far about 25,000 have received their documents while another 40,000 have been approved. The Dominican government says 66,000 people have returned to Haiti since the deadline.
