Temporary protected status for Haitians displaced by the 2010 earthquake in their Caribbean homeland was extended through July 2014.
Haitians previously approved to temporarily live and work here originally had until Nov. 30 to register for the 18-month extension.
U.S. Citizenship and Immigration Services this week pushed back the registration deadline until Jan. 29.
Officials say that's due to "the impact Hurricane Sandy has had on regions were Haitians reside."
The New York City area has a large Haitian-American community.
Sandy devastated parts of New York, New Jersey and Connecticut, damaging or destroying hundreds of thousands of housing units and businesses.
