If I have previously been approved to reside in the R.O.C. before my employment engaged in professional work, do I still meet the requirement of "first time residing in the R.O.C. for the purpose of work"?

If you have previously been approved to reside in the R.O.C. before your employment engaged in professional work in the R.O.C., such approval is not given because of your engagement in the professional work (such as residence for study or as dependents); therefore, you are exempt from the first-time approval limitation.
