Hello.

I am a non-resident alien living in Denmark. I work as an independent contractor, selling products to European distributors for an American company. I live and work in Denmark.

I am in the U.S. about 10 days per year to meet with the American company.

Must I file a return? :confused:

If you are a U.S. citizen, yes, yu must file a U.S. tax return.

Otherwise, no tax return is required for just a 10-day visit.
