AUSMA - I did what you're trying to do some 16 years ago, picked the US and have never regretted it... Having said that, things have changed greatly since 9/11 so it will be more difficult for you now...
The most important thing won't necessarily be the flight school but rather the kind of visa your flight school can sponsor you with as you'll need to build some flight time before you return home...
PM me if you want and I'll be glad to give you my take on things... I have no connections to any current flight schools out there but will be glad to share the 'steps' you'll have to take to start your training here...
Be careful - lots of greedy folks out there who’ll try to take an advantage of you... Do your homework before you spend one penny (or centas
) whether in the US, Canada, UK or anywhere else...
