Ireland, UK, or Australia for Medicine for International Student?

Ultimately you should aim to do your medical degree where you want to work. So work backwards from that. This is because getting your medical degree verified to work in another country is expensive and time consuming in most cases, and there is no absolute guarantee it will be. Also there may be immigration restrictions on working in particular areas/fields - for example in Australia, you need to basically either be in a shortage area (not all medical specialties are shortage areas) or working in an area that is underserved (i.e. rural regions). This is true whether you do your degree there or not in principle I suppose, but is something to bear in mind and the structure of one country's medical training may make it easier or harder to meet those requirements.

Additionally bear in mind getting a medical degree in the UK does not allow you to be fully registered with the GMC on graduation - you need to complete FY1 to achieve that, and you have only a set number of years to complete FY1 and achieve this. Therefore in the UK unless you never planned to ever work in the UK medically again, if you get a medical degree here you also need to plan to work here for at least one year (and practically it probably makes sense to complete the foundation programme here before applying elsewhere). This may affect your plans for the future as a result.

Also the medicine community discussion forum is for UK medicine specific questions and international ones would belong in this forum

Thank you for the response and clarification on the forum section.

Once you do the FY1 in the UK, are you guaranteed registration with the GMC? Also FY1 is 2 years right?
I'm trying to figure out where it is least difficult to get a job and get registered as a doctor post-graduation for an international student. I am also thinking of other factors, such as work life and hours. Assuming there is no preference for location post-graduation and the person will work where he/she will graduate, where would you advise an international student to study medicine?

FY1 is one year, FY2 is the second year of the foundation programme (but you are fully registered with the GMC by then, in principle, I think). I think if you complete all the requirements for passing FY1 you will be able to register with the GMC without any issues? Maybe if you have some undeclared fitness to practice issue which hasn't come to light until that point it might not necessarily "guarantee" it but I think that's maybe an obvious exception. However I'm not that certain of how it works in practice since I am not a medic! @ecolier might be able to give more advice on that.

In general though in the UK, once you get onto the medical degree as long as you meet the minimum requirements to progress you're basically guaranteed to continue to through the degree and into a foundation post and presumably hence to GMC registration. However bear in mind that is just the start and then you have FY2 and either GP or specialty training, and that is not necessarily guaranteed (although some specialties in some regions are routinely underfilled so if you applied there to that specialty you would basically be guaranteed a spot if you meet the requirements - possibly even having an interview waived if you score enough portfolio points. For GP training in some areas they'll throw in a free £20k golden hello too!).

Of course it's possible actually meeting those progression requirements is hard (such as it is in many European medical schools where they let in almost everyone but only the top X proportion of students will continue to subsequent years of the medical degree) but UK medical degrees have very low drop out/fail rates so I think that's less of an issue. The hard bit is getting in, to a point!

Not sure how Ireland or Australia specifically compare to that, except for in Australia you will be basically guaranteed a training spot if you go for one of the undersubscribed rural locations - and in fact at least Australian students (not sure about international students) may be offered a "bonded" place which is fully funded by bursaries that don't need to be paid back, on the proviso that you must work in one of those regions for a fixed number of years after graduating (to meet the need for doctors in severely undersubscribed regions, mostly in the outback and such). Of course, if they don't do that then they have to repay the whole thing themselves...

Thank you for the detailed response.

Do I have to take the AMC exam if I graduate from Australia?
For the UK, as you explained, I don't think I have to take the PLAB exam after graduation right?
