The Portugal Job Seeker Visa is initially valid for 120 days, or approximately four months, allowing applicants ample time to search for employment. If necessary, this visa can be extended once for an additional 60 days, giving applicants a total maximum stay of 180 days. It is important to note that the visa is valid for a single entry only, meaning that if you leave Portugal during this time, you cannot re-enter using the same visa. Therefore, applicants are advised to carefully plan their travel and stay in Portugal to maximize the time available for job searching.
