I spoke to the folks at HR today and they say they are aware of the problem with the assessment. It came up last week with a Canadian pilot who does have a green card. If you want to email them, Corpjet, you can PM me and I will give you the email address of the woman to whom I spoke. She said they are going to contact those who had a problem with that portion of the assessment and should send an email to those applicants in a few weeks. You may want to wait for that email.
All I can say is to keep on top of it and good luck.
Mike
