Which English speaking countries (or with a strong English speaking market) are renowned for having the best visa opportunities for students who've recently graduated? Would Australia be a strong option? What about Canada?

Thank you.

Looking at the FT data for international mobility, it looks like Australia has just two top-quality schools, but they have better mobility than the four Canadian schools. This could be useful: https://e-gmat.com/blogs/working-after-mba-in-europe-canada-australia-visa-and-immigration/
