Unless what you’re saying is they are still issuing Transfer Options and you want them to give you one.
In that case, IMO, it might not hurt if you send them a letter asking for one. Along the lines of my 6th paragraph above. Also including what you will do for them if they admit you; ie what’s in it for them? (like you would participate in this, that or the other thing…) With any new qualfications that may have arisen.
It would be good to know whether you are even remotely in the mix for this (can GC find out ?), and also whether they are still issuing Transfer Options, at this point. But without this information you could still lob in a letter, why not?
