Thank you for your and and suggestions. I am licensed in Minnesota, which is not part of compact states. So I am unsure if after getting endorsement to Texas or Ohio, I will a single state or Multistate license. My feeling is single state. You had mentioned in # 4 about original CGFNS-visa screen certificate ( do you mean when I got assessment for Minnesota license). If that is what you meant, It was done many years ago and I am unsure if I have that record. I can ask CGFNS about it.
I am trying to figure out if it is better to get TN visa by myself and try different states, or work with an agency for a specific assignment.
