Participants requiring a visa to enter Portugal are strongly advised to apply in their home country at least three months before their intended travel date. If unsure, you can obtain information from your nearest Portuguese Embassy or Consulate, or through your travel agency.
Based on previous experience, we know that visa applications can take a considerable amount of time to process. Please apply for a visa well in advance to allow enough time to resolve any potential issues.
