Yes, the Portugal Job Seeker Visa can be extended once. After the initial 120-day period, if you have not secured employment but can prove that you are actively searching for work and still meet the visa requirements (including sufficient financial means and health insurance), you may apply for a renewal of up to 60 additional days. This extension provides extra time to attend interviews and finalize potential contracts. However, no further extensions are granted beyond this period, making it essential to secure a job within the allowed timeframe.
