I would agree that we are certainly seeing better approval rates for applicants coming from Asian countries than from several African countries, and I don't always know why this is.
At times it has been incomplete applications or issues with document translations. Of course, we have a very capable and multilingual team here, so French doesn't pose issues per se. However, in the case of some other countries, if documents are not in English, of course this could cause some delays and then might have a snowball effect on them. They might have to defer their studies and maybe consider other options as well if they can't begin their programs in a timely manner.
