Dr Esteban, if you haven't flown in the USA before or haven't flown much in the USA make sure you read up on the rules and regulations before you come over, and get a good understanding on how to interpret sectionals and terminal charts. Also have time with an FAA instructor just to put it all into practice. I often witness terrible flying from foreign (non-US) pilots who have little understanding of the most basic of procedures especially in the pattern, for example the 45 entry, default pattern directions, CTAF use, etc.
