Visitor Visa Extension for Clinical Attachment

Greetings of goodwill, fellow doctors! I hope this message finds you well. :pray:

I was wondering if anyone has applied for a visitor visa extension on the the basis of doing a clinical attachment? It would be extremely helpful to hear about your application experiences, timeline, and what you would have done differently. :blush:

Personally, I am planning to do a clinical attachment in June-July (after completing PLAB 2), however, my visa was issued a month earlier than expected (it expires late June). Hence, I am currently looking into the possibility of a visitor visa extension.

Any suggestion / advice will be highly appreciated!
