International Visitors

CAMX is excited to welcome our international attendees to San Diego for an inspirational learning and networking experience. Your participation brings a vibrant and diverse perspective to the event, and we thank you for choosing to be part of CAMX.



To travel to the United States, a U.S. visa may be required. Please read the information below carefully and reference it as needed.

Step 1: Plan ahead.

Current visa services and operations vary by country. Check your local U.S. Embassy and Consulate’s website for information regarding operating status and which visa services are currently being offered. You can also check the estimated wait time for U.S. visa appointments in your country.

If you’re a citizen of one of the 38 countries participating in the Visa Waiver Program, you may travel to the United States for tourism or business for 90 days or less without obtaining a U.S. visa.

Step 2: Register and request your letter of invitation.

To obtain a letter of invitation to CAMX, we strongly urge you to place your request for a letter as soon as possible. Once you register, click on the “print visa letter” button or log in to your existing registration record in the Attendee Service Portal and click on “Visa Information” in the My Account drop down menu. Print the Letter of Invitation, in color, and submit it to the U.S. Embassy/Consulate with your visa application. If you have any questions, please contact

Please note that this letter is supplementary information that explains an applicant’s intended travel purpose. U.S. Embassy officers look at the totality of an applicant’s personal and professional situation—the letter itself will not guarantee your application’s approval.

Step 3: Determine which type of visa you need.

Your travel plans play a part in the type of visa you need (just business, or travel/tourism and business, etc.). You can use this online tool from the U.S. Department of State to determine which visa category is most appropriate.

International media visa requirements—Please note that members of the international media must have a non-immigrant media (I) visa to attend. Additionally, citizens from a country participating in the Visa Waiver Program (VWP) who want to enter the United States temporarily as representatives of the foreign media, engaging in their profession as media or journalists, must first obtain a media visa to come to the United States. They cannot travel without a visa on the Visa Waiver Program, nor can they travel on a visitor (B) visa. For further information on the media (I) visa please click here.

Step 4: Complete the U.S. Visa Application form.

See the U.S. Department of State’s website for the complete list of documents you may need for your application, then complete the U.S. State Department Online Non-immigration Visa Application. Once you complete the online application, a confirmation will be emailed outlining further instructions for an appointment.

Step 5: Schedule your visa appointment.

Select your country of origin and create an online user account, if necessary. Then enter the confirmation number from your visa application and follow the instructions for application submission and required fees to schedule your visa interview.

Step 6: Prepare for your visa interview.

Bring all of your materials related to CAMX to your interview, including your Letter of Invitation, hotel and flight reservation confirmations, your meeting schedule (if applicable) and any other documentation supporting your participation in the event. You should also be prepared to demonstrate strong ties to your country. Consular officers review your application and consider proof of business ownership or employment, social and family relationships and other evidence as proof that you will return to your country. If you have traveled to the U.S. or other foreign countries, you may also want to bring documentation showing that you returned on time.

While we make every attempt to keep this page up-to-date, please note that regulations may change. The best resources for accurate information about the visa application process are US government websites. CAMX cannot intervene with US Embassies or consulates abroad or with the US State Department on behalf of any member or CAMX meeting attendee.
