u/Blueberry-Which

Hello,

I am an F-1 rising senior in a Physics BA. I am interested in doing a PhD in medical physics. Due to financial restrictions, I may have to leave the US to pursue an affordable masters elsewhere first then reapply for PhD. I know that if I want to be accredited in the US, one option is to attend an accredited program.

1-But how does residency in the US work if your most recent degree is not from the US, so you can't be on OPT. Is residency then contingent on getting a H1-B sponsorship?

2-If so can international residents share their experience or what they know about how often people in this case get admitted to and attend residencies?
