Information on Portugal’s Tech Visa program is available from the Portuguese government agency responsible for innovation and competitiveness (IAPMEI) and from the Ministry of Foreign Affairs. The program is designed to certify innovative and tech companies so that they can more easily employ highly qualified professionals from outside the European Union. Detailed criteria include what companies need to do to obtain certification, who qualifies as a “tech professional,” and what visa / residence permit steps are necessary. There are also official resources describing how to apply, what documentation is required, and how long the process takes. These sources are updated periodically with new information, so always refer to the government-issued official pages for the most current guidelines.
