Thank you for your question.
First of all, it depends on the country.
Funds are one key reason. I think one of the biggest source countries we have for student movement where that was an issue is Nigeria. In Nigeria, we have gone to great lengths to put in a new program where we can better examine, with the co-operation of the Nigerian government and the Central Bank of Nigeria, a real source of funds around that, in trying to reduce some of those integrity concerns so that we have a smoother pathway for students coming in.
