and will hopefully have enough to start at the beginning of March.
If you are seriously considering coming to the US and starting a Private cert at the beginning of March you need to get your skates on. Also get your medical done before you spend any money on anything else.
You need to get your Flight School sorted/booked and paperwork completed then get your visa application submitted (~$300) then when that is finalized, get your TSA submitted (~$140).
Presumably you haven't started your written exams yet? You really need to have them all completed first.
How long are you allocating for the training from start to end?
Remember that the USA JAA Flight Schools only quote a price based on the minimum number of hours and a first time pass. You need to cost out an additional 10 hours minimum as a contingency and remember medical insurance and renters insurance prior to first solo etc. if you take longer than the planned timeframe, you may find that the 'accommodation' costs will kick in.
