You're in the wrong forum.
Hi Flower fly2012,
This is the 'Private Flying' forum and as such is essentially for those who fly mainly for recreation.
Since you seem to want to be a commercial pilot, you would be much better advised to read, and post your questions, on the 'Wannabes' forum.
I suggest you read a lot of the wannabes' stuff first as I suspect it will answer many of your questions.
You don't mention whether you have taken any of the CPL or ATPL ground exams yet. In my experience, by far the hardest part of the route to becoming a commercial pilot is the ground school. There is no point in going to the States, or anywhere else for that matter, until you have passed all the ground exams for whichever licence you are working for.
Good luck,
BP.
