hey nicolas, i'm from argentina too but i have to speak english here for the sake of not being removed by the moderators....
you can pm me and i talk to you more...but being only 18 years old and with the private only i think you have 2 options: a) come with a lot of money and buy hours in USA or somewhere else, and get more ratings.....or b) join the EJERCITO ARGENTINO...you have more chances there...just stay and they train you and you get to fly some hours......
ok...pm me if you want more info.
