Sadly same thing happened here. I sensed something was wrong, the job offer was too good to be true and they were very flexible. What made me doubt the whole thing before even sending my personal documents was that I googled the name of the school and found nothing related to it!! How could a school that is paying that huge amount of money doesn't have an actual known profile on the internet. I kept denying my feelings of doubt until I saw this post now while searching using the school's name again. Thank you for letting me know, you saved me a lot of hassle, but I do regret sending my personal documents now I hope they won't be using any of it in any illegal act.
