It all depends on yourself. It's not HAI who does the trick. It's not just going to the States get you CPL/CFI and everybody's waiting for you.
A school adds to your own qualities in the first place. Ie. rubbish in, rubbish out.
It's very simple of 100% enlisting 80% gets a PPL, 80% of that makes it to CPL/CFI. (Might take 'em quite a long time). Then you might find a job and build up hours.
Then people return to Europe with 300-1200 hours. Yes, a very broad range. If you did the JAA in the US, you might find a job here. But if you didn't do JAA you have to study for another 6-9 months and a lot of guys just quit.
I discovered an awfull lot of ex-HAI guys don't even fly anymore.
By the way I'm not one of them. I'm only telling you the way it is.
