What you need to bear in mind with regard to your visa
For your visa application: invitation letters for visitors
As part of the organizer’s communications to each prospective overseas participant, we encourage you to stress the importance of reviewing any existing U.S. visa the participant may have and to apply early for any new visa required. Please visit http://travel.state.gov for more information.
Advance planning by foreign travellers is critical. We recommend all foreign travellers consider the following when making their plans to travel to the United States:
- As soon as travel to the U.S. is considered, foreign travellers should identify whether a visa is needed.
- If the traveller already has a U.S. visa appropriate for this travel, check the expiration date on the visa to make sure it will not expire before the planned travel date.
- Each applicant should contact the U.S. Embassy or Consulate Consular Section in his or her country of residence to determine any additional visa procedures, including the time frame required to schedule an appointment for the interview. An interview is required for most visa applicants.
