Hi,
If you guys are thinking about conversion to FAA licenses in the States, your best bet is to do the training at a Part 61 not Part 141 school, as there is no 3 month security back ground checks done for that.
On saying that do your research before heading to Miami, contact Airborne Systems in Ft Lauderdale (141) and American Flying Club (61) and see what they have to say. re papers needed.
Or
Go to a flight school in the Carribean, pay more for fuel and then fly back to the states to do your checkride as long as all paper work is complete.
