Visa Information

Invitation letter

If you do require visa, the organization will be pleased to give you a letter of invitation for your visa application. Visa applications are to be completed to the nearest Portugal embassy or consulate to you. The requirements of Visa applications and documents needed are to be requested from the concerned Portugal embassy or consulate. Portugal diplomatic missions in the world can be seen on the link: Please note that nanoTECH/ECAT does not accept any responsibilities for the accuracy of the information under this link. The letter will be send by e-mail only. Please be aware that we won’t be able to contact directly consulates or embassies and we do not intervene in anyway with the Visa process, as the participant is solitary responsible to apply and follow up on his Visa application.


In case the concerned consulates or embassies contact us, we will not be able to support the participant Visa applicant unless he/she is fully registered to the conference and has paid the registration fees. For this, we strongly advise our participants to register to the conference before applying for the Visa.
