Having just spoken to someone at Flight Safety; they are saying that PTC contract ended because of immigration problems.#
Apparantely they were conducting their own ATPL groundschool and some of their IAA flying training - without Flight Safety involved and this is against US immigration law. Flight Safety provide the visa or any school which provides your training, must be the one to provide your training or in conjunction with, if you start training outside that; then you have terms for visa termination.
When Flight Safety raised this apparently PTC started being more vague. Flight Safety didn't want the risk so didn't want the PTC contact anymore.
