Visa Information

We are honored to have you attend the 2017 CNS Annual Meeting. Use the following information for ensuring a successful visit to the United States.

Apply Early for Your Visa

We urge you to apply early for your visa. The U.S. State Department advises that an application for a temporary visa to enter the United States requires a longer processing time than in past years.

The decision to grant visas belongs solely to the embassy or consulate. We cannot promise that you or your colleagues will receive a visa. Should your application be denied, we cannot change the decision of the governmental agency.

International Invitation Letters

In order to grant your request for a visa letter, we request your:

  • Name (required)
  • Address (required)
  • Passport number (optional)
  • Date of birth (optional)

For more information about requesting a letter, contact us.
