Even if you have an SSW residence card, you cannot freely start working at a new company when changing companies. If changing your accepting organization under SSW, you need to apply for permission to change status of residence. Do not work at the new company before permission is granted.
What to Check Before Changing Jobs
Check whether the new company offers work in a field and job category accepted under SSW. If the field changes, you may need a skills exam for the new field.
Check the new company's salary, deductions, dorm fees, work location, support details, and registered support organization. Do not decide by salary alone.
Write down your last day at the old company, start date at the new company, and planned application date so the gap is not too long.
It is risky to stay for a long time without doing activities that match your status of residence without a valid reason. After leaving a job, move to the next procedure quickly.
