Don't try to read more into it, than you have to. Flying here in the States is no different than flying anywere else. Of course we have more Aviation than most countries, and the FAA makes it as simple as it can, in these I will sue for anything times. You are doing a Multi Rating here, by the time you get that done, you will be fine with how things are done here. The Dirty little secret here is that you could fly from one end of the country to the other and not have to talk to anybody if you so choose. You go over to Orlando a couple of times with your Instructor and the rest will be a piece of cake. I would suggest that you get a US sectional chart, don't matter which one, and read it. Most of all you are going to need to know is printed on the chart. While at it get a copy of the FAR/AIM. Read part 91 once or twice, keep a copy to refer to while flying, outside of some language differences, most of the Rules are pretty standard no matter where you fly.
