Another interpretation of 'your options will be limited' is that you must rely a lot more on 1) diligence including doing your homework on programs/labs/institutions that are open to FMGs and 2) luck. I highlight #2 because that's the major component. I was working in an academic institution and I think all the small pieces fell into place that the division hired an FMG and who later published quite a handful of nice papers with the group. Work hard, throw your CV out there, cast a wide net, and pray.
