The S Pass allows mid-level skilled foreigners who earn a fixed monthly salary of at least $1,800 to work in Singapore. Employers must make S Pass applications on behalf of a job candidate.
S Pass applications are approved based on multiple criteria's like salary, education qualification, skills, job type and work experience.
The Work Permit (WP) is issued to basic-skilled workers who want to work in Singapore’s in-demand sectors and are from approved source countries. The duration of a WP is two years, subject to the validity of the worker’s passport, the Banker’s/Insurance Guarantee, and the worker’s employment period, whichever is shorter.
