SANTO DOMINGO, Dominican Republic—The Dominican Republic has announced a new crackdown on illegal immigration that will lead to the ouster of thousands of Haitians who escaped a devastating earthquake last year.

Immigration Director Jose Ricardo Taveras said Wednesday that migrants lacking appropriate documents will be deported immediately.

The proposal was signed by President Leonel Fernandez and aims to classify all migrants according to their work and migration status for the first time in the country's history. It will also afford them proper identification.

The government did not provide further details about the plan nor say when it would act on it.

The plan is part of a 2004 immigration law that seeks quotas for foreign workers.
