Depending on the situation, we can be talking about different work permits. A D1 Visa (Residence Visa for Subordinate Professional Activity) is suitable for those who want to live in Portugal and work here by signing an employment contract with a Portuguese company. A D2 Visa (Residence Visa for Independent Professional Activity and for Entrepreneurial Immigrants) is suitable for those who want to work as an independent worker (e.g. lawyer), as a service provider (e.g. freelancer or digital nomads) or start their own business with the creation of a company in Portugal. A D3 Visa (Residence Visa for Research Activity or Highly Qualified) is suitable for those who have been admitted to a research center or exercise a highly qualified professional activity.
