Currently, foreigners can establish a company in Portugal online with the assistance of an authorized agent. However, non-EU residents must secure a visa to open a business in Portugal. Portugal has announced plans for an e-residency program, but it has yet to take off. In the meantime, there are several pathways for non-residents to get a visa to start a company in Portugal. Options include the Golden Visa, which requires a minimum investment in specific investment classes.
By contrast, Estonia's e-Residency program does not require a visa, relocation, or the assistance of an authorized agent. E-residents can
start a private limited company or OÜ in Estonia entirely online. If their company's management board has a foreign address, they simply need to designate a local contact person in Estonia.
