After Brexit, will it be easier for a Latin American student to find a SA internship in the UK?

Hello everybody,

I am a final-year student at a Latin American university. I'm hoping to pursue an MFin degree at LSE and eventually land an IB internship/full-time role in the UK. I understand that there is now a new job policy in the UK that allows foreign graduate students to stay in the UK to work for a maximum of 2 years after the completion of their degrees.

Adding the Brexit factor to that, would I be as competitive as an EU student when applying to the internship/full-time role? Or is there any regulatory framework that makes them less expensive for an IBank than a Latin American student?

Many thanks in advance
