It depends on the type of business, the money that will be spent and the role of the investor in a business.
The permanent resident permit for property owners does not provide access to any type of employment. Employment, according to paragraph 6, article 20, of Law 4251/2014, does not include the exercise of economic activity in the capacity of a shareholder or a chief executive officer for an already existing company. Under the above conditions, you should proceed to exercise your business activity.
As it is explicitly provided for by the Greek law, the Greek Golden Visa does not give right to access to any type of employment, according to Article 20, paragraph 6, Law 4251/2014. Employment in this case does not include the exercise of economic activity in the capacity of a shareholder or chief executive officer of companies established before the application for the Greek Golden Visa. This exemption for economic activity includes also the shareholders or managers
of all forms of capital companies (S.A., ltd., private limited companies). Subsequently, as a real estate property owner in Greece and holder of the Greek Golden Visa, you can only work under the above conditions.
You can establish your own company in Greece with no limitations. You will need to consult with a lawyer in Greece explaining your business plan, the type of your company and all the other details.
