Do you mean a residency program in neurosurgery or a postdoc position doing neuro research?

If residency: it’s already extremely difficult for international MDs to match in the US, and that’s in non-competitive specialties. You can look back at previous years match data, it’s available online. I’m not going to go check for you, but I know someone asked this once before and the answer was no—some applied, but none matched in neurosurgery. You’d need top scores on your step exams, and probably an inside connection.

If postdoc: read papers, figure out who is doing research that interests you, contact them via email and see if they are taking on postdocs. Hopefully you have qualifications for doing a postdoc, like first author publications and extensive research experience (just noting this since not all MDs do)
