I don't remember the name of those places right now, but I suggest you give a look at sites like FlightSchoolDB or BestAviation, you may find schools in Oregon, Ohio, Minnesota and so on.
You do not need any visa for hour building, so you will have a lot of options to choose from. It doesn't have to be a flight school. An aircraft owner that rents his aircraft out is a good option too. If you can find one.
