What visa for a short term course in the USA? There is a short term course in the USA in August I really want to attend.
It's a 1 week training at the University of Minnesota. However, I'm not going to enroll as a student at the university.

May I use the B1 visa to do so? Has anyone been in a similar situation?
I am not a lawyer and this is not legal advice, but my understanding is that B1 visas are typically the right visa for academic conferences and similar events.  See this document from the US government, particularly the entries on “Conference, meeting, trade show, or business event attendee” and “training.”
