General information

From the website of the United States Department of State:A citizen of a foreign country who seeks to enter the United States generally must first obtain a U.S. visa, which is placed in the traveler’s passport, a travel document issued by the traveler’s country of citizenship.

Certain international travelers may be eligible to travel to the United States without a visa if they meet the requirements for visa-free travel.

A resource that should be helpful to those persons seeking a visa for travel to the United States can be found on the Department of State’s website at https://travel.state.gov/content/travel/en/us-visas.html. At this location, travelers can find a “Visa Wizard” that can be useful in determining the type of visa required, a listing of frequently asked questions, estimates of visa appointment waiting times, and much more visa-related information.

Invitation letter

From the website of the United States Department of State:A letter of invitation or Affidavit of Support is not needed to apply for a visitor visa. If you choose to bring a letter of invitation or Affidavit of Support to your interview, please remember it is not one of the factors used in determining whether to issue or deny the visa.

Although a letter of invitation is not required, some visa applicants may wish to acquire this additional document. Generally, the purpose of the letter would be to show the United States consular officer who considers the visa application that the applicant has a specific plan regarding visiting (and eventually leaving) the United States and has a legitimate purpose for the visit.

Persons planning to attend an event at or affiliated with Colorado School of Mines can request a letter of invitation through this website.

If you do not already have your passport, acquiring an invitation letter will be of little use, since the embassy or consulate at which you request your visa will likely not consider your application without your valid passport information. Nevertheless, you can use this website to request a letter even if you do not have a passport.
