If a full-time foreign speaking teacher would like to change their employer or have one or more additional employers, each new employer should apply for a new Work Permit for the foreign teacher. When applying for the new Work Permit during the valid period of an exist Work Permit, the new application can be exempted from providing the medical examination report, under the condition that the original medical examination was certified and proved to have been passed. The new employer would still need to attach the copy of the original/existing employment permit and provide a reason why the medical examination certificate is exempted.
