Back in January of 2010, the U.S. government authorized citizens of Haiti who were in the U.S. at that time -- when a major earthquake hit their country -- to remain,by applying for what's known as "Temporary Protected Status."
The original deadline by which applicants from Haiti who successfully obtained TPS were then expected to leave the U.S. has since passed, but been extended. Theextension of status is not automatic. TPS recipients wishing to remain in the U.S. with TPS status must apply to extend it accordingly.
While the deadline for re-registering had been set at May 2, 2014, prospective applicants have been given a reprieve. The new deadline is July 22, 2014. This will allow continued TPS status until the current deadline of January 22, 2016.
See the USCIS press release, "Temporary Protected Status Re-registration Period Extended for Haitian Nationals," for details.
