Invitation Letter Request
IIRRM cannot accept any responsibility for Visa applications nor will it influence the processing of Visas. It is the sole responsibility of the attendee to obtain the necessary paperwork for entry to Croatia. You are responsible for applying for the appropriate visa with the proper documentation. All expenses related to the event and visas are the participant’s responsibility. The Congress invitation letter is only issued upon completion of registration and payment of the registration fee. In case that the visa application is refused by an Embassy/Consulate Office, no refund is processed. As we are a hybrid event we will switch your registration to an online delegate which allows you to participate in the Congress, earn CME and interact with other delegates and speakers.
Please send your request to anne@iirrm.org with the subject line ‘Visa Invitation Letter’.
