Register for the conference and reserve your hotel through the IOHA block to save money and receive preferred accommodations. Although English is the official language of IOHA Washington 2018, online registration and hotel reservations are available in several languages.

Documenta​tion

AIHA can provide documents to assist in obtaining permission to attend the conference; however, AIHA cannot intervene with any government agency on behalf of a participant:

  • Official Letter of Invitation: AIHA can write official letters of invitation to participate in the IOHA Washington 2018 conference. This letter may NOT be used with your Visa application. Email AIHA to request a letter of invitation.
  • Official Letter of Registration for Visa Applications: Once you have registered for IOHA Washington 2018, you will be provided a Letter of Registration for Visa Applications. You may print and submit this letter with your Visa application to verify the name, dates, location, and purpose of IOHA Washington 2018. Letters of Registration for Visa Applications will not be made available to anyone who has not registered and paid in full for the conference. There are no exceptions to this policy. See below for registration refunds due to Visa denials.

Visa Del​ays or Denials

Visa processing may require a long lead time. We highly recommend you apply for a visa three (3) to four (4) months in advance of the conference. If your visa is denied and you would like to be considered for a registration refund, make sure you have an official denial document or a stamped copy of your application form with the date of application and date of denial. Email copies of these documents with your refund request.
