E-7 visa holders are often told they cannot leave their job because the employer will not issue a "release letter." That belief traps many foreign professionals in poor conditions. In fact, Korean law regulates the move through a formal workplace change process, and there are clear situations where you do not need the old employer's permission at all.
The workplace change procedure
The E-7 visa ties you to a designated occupation and employer. Moving to a new company is a workplace change (근무처변경, geunmucheo byeongyeong) governed by the Immigration Control Act (출입국관리법, Chulipguk Gwalli Beop). How you process it depends on your occupation category.
- Prior-approval occupations: for many E-7 roles you must obtain permission from Immigration before you start working for the new employer.
- Post-reporting occupations: for certain designated occupations you may begin the new job and then report the change within the required period.
Starting the new job before completing the step your occupation requires is a common and serious mistake, because working outside your authorized scope can itself be a status violation that endangers your visa.
When you do not need the employer's consent
The release letter is a practice, not an absolute legal gate. Where the previous employer is at fault, you can generally change workplaces without their consent. Typical fault situations include:
- The business has closed or is unable to continue operating.
- Wages have gone unpaid, known as wage arrears (임금체불, imgeum chebul).
- The employer breached the employment contract, for example by changing duties or conditions unilaterally.
In these cases you can document the employer's fault and apply for the workplace change directly. Evidence such as pay records, the signed contract, and any labor-office complaint strengthens the application considerably.
Why documentation decides it
Immigration looks at the substance, not at labels. If you simply found a better offer, you will usually need the proper process and, depending on the occupation, cooperation from your current employer. If the employer is genuinely at fault, your proof of that fault is what replaces the release letter, and the burden is on you to show it clearly. Gathering the evidence before you resign is far easier than reconstructing it afterward, when access to payroll records, internal messages, and witnesses may be gone. Keep copies of everything while you still have access to the workplace.
Get the sequence right
The order of steps, and whether your role needs prior approval or only reporting, can decide whether your status stays valid. A licensed Korean attorney, Sangbin Min of Daejin Law Firm, advises foreign professionals on E-7 workplace changes, including cases where the employer's fault lets you move without consent. A brief consultation before you give notice can keep your visa secure throughout the transition.
