A non-native speaker needs help with the following phrase to be used in the acknowledgments section of a research paper:
"Parts of the this research were conducted during a visit of the International Law Group of Kalamazoo Law School."
All authors of the paper visited that place. I'm especially not sure whether it should be "visit of", "visit to" or "visit at". The length of the visit in question was six months. Maybe I haven't even listed the correct option.
