Once you are granted a resident permit for self-employment as the business owner and director of the company, you have to enter Germany at least once in a half year. You can still maintain your residency in your home country where you will spend most of time. However, you will have to have a registered residence in Germany as well. Otherwise the German authority would not have enough reason to believe that you need a long-term resident permit for you to run your business in Germany. Our tip to save costs: You can register your company under your residence address in Germany as well.
