A new pass was introduced last year by the MOM which is similar to an EP but not tied to any one employer. It is valid for 5 yrs and gives an expat worker up to 6 months to find another job in Singapore before the pass is invalidated. The pass is a 1 time issue and at the end of the 5 yr term can't be reissued, the only option then for an expat who wishes to stay for further lenths of time in Singapore is to get PR.
