A letter from U.S. employer detailing nature of employment in the
U.S.
The employment must be temporary. The letter from the U.S. employer
must state that employment is temporary. A person in TN status can later
apply for permanent resident status based on the same U.S. employment.
However, at the time of the TN1 application, the applicant cannot intend
to remain in the U.S. permanently.
There must be no strike or lockout at proposed worksite. If there
is, USCIS may deny the entry.
