1) no one can accurately assess your chances, so these threads are typically not answered but I will offer some thoughts...
2) work experience outside of the US is generally considered, especially the surgical fields, a detractor. US residency programs often find that previously trained physicians are difficult to untrain, do no respect hierarchy (ie, have difficulty becoming an intern again), and refuse to learn how things are done in the US.
3) all FMGs have 99/99 so these scores are actually somewhat expected (and it is assumed that you have spent many many more months than US students studying for the exams, hence the high scores)
4) MRCS - not helpful in getting into a US residency. Research is only helpful if first author, major journal recognized in the US and at academic programs.
5) There are a *few* US surgical fellowships which do not require Board Certification/Eligibility by the American Board of Surgery (which requires a US surgical residency); you might be eligible for those. Otherwise, residency usually comes first and then fellowship. Sometimes you can do a fellowship first, make some connections and then get into a general surgery residency.
Surgery in the US has gotten fairly competitive. There are few open spaces but I cannot say that you (or whomever you are posting about) doesn't have a shot. Other important factors: citizenship/need for visa, US contacts/LORs, US electives/experience, length of time since graduation.
But the bottom line is that no one can give an accurate assessment of someone's chances because there are so many variables involved. Suffice it to say that whomever you are posting about has an uphill battle.
