BROOKLYN - Caribbean teachers in Brooklyn say they are still waiting for immigration help that was promised to them by the city. Some immigrant teachers say they expected permanent status about a decade ago, when city Department of Education officials recruited teachers from the West Indies to help with the city's teacher shortage. In exchange, they were offered eventual permanent status, which would also extend to their families. However, the teachers' current visas do not allow their dependents to work, leaving many spouses without jobs. Department of Education officials say they are working to find a practical solution.
