Invitation Letters

An invitation letter is NOT required to apply for a U.S. Visa. Per the U.S. State Department website:

Visa applicants must qualify on the basis of the applicant's residence and ties abroad, rather than assurances from U.S. family and friends. A letter of invitation or Affidavit of Support is not needed to apply for a nonimmigrant tourist visa. If you do choose to bring a letter of invitation or Affidavit of Support to your interview, please remember that it is not one of the factors that we use in determining whether to issue or deny a nonimmigrant tourist visa.

When you register for Metabolomics 2018, you will receive an email confirming your registration. Keep a copy of this email for your records, it may be required with your visa application.
