Thank you for the replies and suggestions.
The school my daughter attends is international and the administrators are in another country. They helped us to obtain accommodations for my daughter, but they don't assist with finding a place to take the exams. I also found out this morning that College Board can tell you which schools don't take outside students. The names of the schools I had previously been giving by College Board don't take outside students, and I was given those names in error.
At this point, it looks like we might be going to NYC or Philadelphia for her to take the tests.
