Beware of Unscrupulous US Visa Advice
I'm in possession of emails from flight schools from the US who state that you do not need a visa to enter for PPL training.
This is INCORRECT. Take note of previous posts on pprune, and, having just spoken to the US embassy, you NEED a visa to enter for any type of training.
It has been suggested by "professionals" to enter on the Visa Waiver and then decide to enroll in your school, not mentioning anything about your real intentions to immigration. DO NOT DO THIS.
To all wannabes, like myself, you have been warned!
