MARACAIBO/SAN CRISTOBAL, Venezuela - Daniel Briseno lives in a poor part of Maracaibo, Venezuela's once-rich oil city, where he checks almost daily to see if a letter confirming he has permission to move to the United States has finally arrived in the mail.
Briseno, who wants to move to the U.S. with his elderly mother, is fed up of dealing with the challenges of Maracaibo, which has suffered from acute shortages of basic services such as electricity and water for a decade.
