Too add to the B visa debate :
There are JAA FIs at flight safety in Vero Beach, using B1 visas. However they DO NOT provide instruction as US Immigration were explicit in telling them that they could not instruct - only attend the meetings and sort of supervise the activities as they are only there for a about a month-two at a time.
Regarding the F1 - Immigration has even put in writing that if on an Approved course (has to be approved by an accredited authority) then CPT to build towards the ATP is how CPT would be used. OPT is always at the discretion of US Immigration even if the school recommends it.
What this all comes down to is certain schools lying to instructors who do not realise they are working illegally and it is actually the instructors responsibility to maintain status, not the schools. These schools thrive on the fact that no one ever reports them so they never have any repecussions.
It proves entirely that the whole US Immigration / TSA system is a complete sham and all for show.
Now isn't it about time a moderator seperated this thread into a different thread.
