Proof of Accommodation for Visa

You must prove where you will live in Portugal. The most secure option is a 12-month registered rental contract. Short-term Airbnb bookings or hotel reservations are frequently rejected by the Ankara consulate.

Alternatively, a "Termo de Responsabilidade" (invitation letter) from a Portuguese resident hosting you can work, but it must be notarized and accompanied by their ID and proof of housing ownership.
