Thanks for that. I don't profess to know much about the Doctors and Dentists Postgraduate scheme. There is however quite a bit of information on
this webpage.
Clearly on that page it says "you plan to leave the United Kingdom when you finish your training.". However it also provides a link to the SET(O) form whereby the person would apply for an ILR visa!
Anyone reading this know whether the holding of the doctor's "training visa" can get a dependent into the UK? If so, presumably the two of them would need to marry before any such application could be made?
Also, whilst he clearly has a valid visa at the moment, could he apply for HSMP now? Because that would certainly give the ability to bring in a dependent.
Apologies for more questions than answers in this posting.
