S pass rejected reason

There are many possible reasons for S-Pass rejection, and without knowing the exact details of your case it is impossible to tell more.
In general, the reasons can categorized as
    - your (e.g. too low education, work experience does not fit job, etc.)
    - the company (e.g. not allowed to hire foreigners, S-Pass quota filled, no efforts to find a suitably skilled local first, etc.)
    - others (e.g. salary too high or too low, sufficient locals can do the job and should be hired first, etc.)
Your company can appeal against the rejection and then MoM will review the case again. But without substantial changes in the information supplied, the result will be the same.

Thanks for info bro !

Thanks in advance bro

S$2200/month is the absolute minimum an S-Pass can be granted for. But MoM also checks whether the pay is in line with the applicant's education and experience - and this salary is underpaid for a degree holder!
In addition, it is not clear what skills you can offer that a local graduate cannot (who has to be hired first, by law).
Have you used the self-assessment tool (on the MoM website) to see under which circumstances you can get an S-Pass?
