Miscellaneous FAQs


UCAR hires and compensates only those foreign nationals who are permanent U.S. residents or who possess an appropriate work authorization for the position being sought. UCAR may sponsor and provide financial and staff support for foreign nationals to aid in their application for non-immigrant visa status, and when appropriate, for permanent residency. Financial support is based upon the funding availability in the hiring entity.


A document stamped or affixed to the bearer's passport that enables the bearer to travel to the United States under the conditions specified for the type of visa the bearer holds. The visa is an approval for the foreign national to travel to the U.S. and ask permission to enter. It does not automatically allow admission into the U.S. nor is it any type of employment authorization.

Denial of Entry

Occasionally there are questions at the port of entry and the Immigration Official may decide to deny entry to a visitor.  Having a visa stamp is not a guarantee of entry.  Anyone denied admission at a U.S. port of entry should remain courteous and cordial with immigration officials.  Contentious behavior may result in "expedited removal," which entails a five-year bar on any admission to the U.S. If you are denied admission, first try to contact UCAR's Immigration Specialist at 303-497-8705 for assistance.  Also make it known to the Immigration Official that you are willing to withdraw your application for admission to the U.S. rather than be subject to expedited removal.  Please remember that the Immigration Official has the final say in whether a prospective visitor may enter the country.


Anyone who is not a citizen of the United States but is traveling to the U.S. to work or visit.
