International Travel and Visa Process

International Travel and Visas to the United States

If you need to apply for a temporary non-immigrant visa to attend the conference, you are advised to apply for your visa as soon as travel to the United States is contemplated and no later than 3-4 months in advance. International participants should start the visa process during June 2021 or earlier. If your country of residence is different from your country of citizenship or birth, it is recommended to start the application process at least 6 months in advance of the meeting. All applicants must qualify for a visa on their own merits under the requirements of the Immigration and Nationality Act.
