Many of the best international doctors are not coming to the UK. They may have done in the past but not any more. They too have read the news about the challenges within the NHS, the training and working conditions. Many of the ones that still come do so to enhance their CVs so that they can access medical jobs in Australia, NZ, etc. It's easier to do that once you have UK qualifications. In fact, many have been taking up GP posts here purely for that reason and leaving as soon as they qualify. Lots of discussion about that recently. This is going on while UK medical graduates are driving Uber, etc because they can't get a GP post.
Main cause of the huge increase in IMG numbers was the removal of the RLMT and the changes in 2021 (post Brexit) to the points based immigration system.
In India the working conditions are much worse than the NHS and there has been a huge explosion of Indian private medical colleges. Unfortunately there are not enough training posts in India after medical school to support all those graduating in India so they look to pay academies or recruitment agencies to go abroad for training. Many come here perhaps as it's the easiest country to get a job as an IMG. Also IMGs are on an equal footing as UK medical graduates. The salaries for senior doctors in some South Asian countries are several hundred pounds a month. Yes, pay is low in the UK but lower in their home countries. That's why they are prepared to come here and train. Many then leave with coveted UK qualifications to pursue jobs globally. Others stay, wait until kids finish uni and leave once they become consultants. Often back in their home countries, at that level they often have chauffers, maids, chefs and get to be close to family and friends. Some IMG consultants have been saying, given the current NHS working conditions, they don't see the point of staying in the UK and training their juniors when they can have a better quality of life back home. I wouldn't be surprised if their exodus may be contributing to the dwindling number of consultants in the UK.
The international doctors that came decades ago when NHS conditions were better stayed, trained their juniors and settled here having had a better experience overall. Out of these, some IMGs however have established powerful lobby groups central to NHS workforce planning. They contribute to workforce decision-making often protecting IMG interests so that new IMGs don't face the discrimination and the challenges they faced in their professions when they started out. They have established training academies to fast track new IMGs into NHS jobs and support new IMGs. Lucrative businesses too. By having a sponsorship licence from the GMC, the whole process of IMG recruitment is smoother. I imagine all this reduces training capacity for UK doctors. Not sure whether the impact of all this on the NHS budget and the training of UK medics is being monitored.
Prioritisation and training of UK doctors, including IMGs already here should be the way forward. Bringing in new recruits while the ones here are facing unemployment is the wrong approach.
