International Attendees

If you are an international visitor that requires a visa to attend the conference, it is very important to start the process of applying for the visa early. Approval for visas may take more than four months for some nations.

For details on international travel to the U.S., visit the U.S. Department of State – Bureau of Consular Affairs.

Supporting Documentation

As a part of the formal application process for a visitor visa, U.S. consular officials require additional documentation to substantiate the stated purpose of the trip. Prior to commencing the visa application process, prospective international attendees to the AMOS Conference should request an official letter of invitation to the event. This letter should be submitted by the attendee to a local U.S. Embassy or Consulate as a supporting document outlining the reason for travel into the United States.

Please note that the issuance of a letter of invitation from the AMOS Conference does not guarantee you will be granted a visa approval, nor does it commit the AMOS Conference to assist in obtaining your visa. It is the sole responsibility of the attendee to collect any and all documentation and fees required for entry into the U.S. The invitation letter cannot and will not be sent directly to the U.S. Embassy or Consulate for you. The AMOS Conference cannot and will not directly contact the U.S. Department of State, U.S. embassies, or consular offices on behalf of any prospective conference attendee.

Submitting Your Request for a Letter of Invitation

In order for the AMOS Conference to issue a letter of invitation, we ask that you provide some general information regarding your attendance:
