please re-read my post.
i think you should take your green card and go to the US.
of course its a great place to go flying.
especially GA is fun, exactly because infrastructure is better and more conducive. (thats why i suggested to have at least the PPL, that helps to fly ;-) )
also not questioning the industry prospects. its not great right now with oil price etc. but people will still fly in the future.
BUT you are falling exactly into the trap i mentioned earlier.
the money you spent in Europe was a lot. i get it. but it was a sunk cost. its (almost) irrelevant when making a decision what to do in the US.
you paid for some stuff that is not required in the US. (you can do your ATP written here in couple of weeks with a Gleim book) Trust me, i know how annoying the European ATP Theory is.
so, ask yourself: i am going to a new country and need to decide what to do.
do i want to become a pilot? what else would i want to do?
the answer of still becoming a pilot is totally legit. and i hope its your answer. (its always nice to have people junior joining the ranks
). but you are shortsighted if you make such a life-changing decision and dont ask yourself fundamental questions.
the primary reason you mentioned about "your parents having spent the money already" is flawed.
