As of March 2021, foreign investment in architectural and engineering services associated with large-sized projects or using advanced technology is no longer subject to foreign equity limitations. Pursuant to GR 25/2019 concerning the engineering profession, foreign engineers are required o transfer science and technology to local professionals, but differently from the regulation on the architectural profession, it does not require them to partner with local engineers. As such, for the purposes of the OECD FDIRRI, it is assumed that no partnership requirement involving equity or revenue sharing mechanisms are necessary; the employment of local engineers and training is assumed sufficient to satisfy the knowledge transfer requirement. Previously, foreign investment in architectural and engineering services associated with large-sized projects or using advanced technology was limited to 67%.
