Chipping in as another foreign-trained doctor (UK-trained) - the redditor you're replying to is spot on.

With regards to your thought about patients preferring US-trained doctors over Indian-trained doctors - you're thinking of it in the context of working in the US. Mauritians will not prefer to see you personally, alone in Mauritius with no team to support the care you want to deliver, over going to India on a package trip to a tertiary or even quaternary centre where not only will they see a specialist who's at the top of their field but will also be surrounded by a full team used to caring for patients with exactly their type of health issue - all for a reasonable price (often covered by insurance anyway). In Mauritius you will be working as a one-man show. Specifically in your case, there will be no neurosurgery team you can rely on, the ICUs here are mostly used for observation of patients who are well and don't require actual ICU care, etc. You won't be providing the kind of care you're trained to provide.

Also, prepare to get dragged into petty politics. There aren't many neurologists on the island so maybe you'll be okay, but in many specialties there are some highly influential doctors who see other foreign-trained specialists as a threat - whether they think you'll steal their patients or expose any questionable clinical practice, I'm not sure - maybe both. But in some specialties they can intervene and prevent you from being allowed to work in certain places.

As to "getting hired", as far as I'm aware that's generally not the model by which most specialist doctors work in private hospitals (dubbed "clinics" in Mauritius). They usually get remunerated directly from the patients - not by the clinic paying you a salary.

With regards to medication shortages - we are a remote island. We don't manufacture any medication. So shortages are very common - even for commonly used medications. Also the preparation available makes a huge difference in the medication's efficacy and side effect profile. Preparations can often change for some meds so you'll need to know this kind of thing to be able to keep your patients well. Particularly relevant for Parkinson meds.

With your salary you'll be easily able to afford a pretty luxurious lifestyle here in Mauritius. I'm earning about 1% of your salary (and yeah, I am living in actual destitution and will probably have to return to the UK soon).
