All guest workers and work permit holders in Bermuda irrespective of rank or seniority are required to sign a declaration acknowledging that they are not entitled to permanent residency on the Island. Those already in Bermuda were required to sign the declaration by April 30, 2013. The declaration policy was introduced to allay fears of a potential surge in permanent residency applications from guest workers who can, if their work permits to do so are renewed, now remain employed in Bermuda indefinitely. But not if they are not in work-permit approved employment or if their work permit is revoked.
