Hi!
Yes, you can absolutely use that additional information section to clarify both areas - it's there for anything you feel hasn't been captured anywhere else in the form.
If the visa question only gives a Yes / No response with no space to expand, it's perfectly reasonable to briefly explain your visa situation here (e.g. that you currently hold a visa suitable for a Vacation Scheme but would require sponsorship for a Training Contract). It's usually best to communicate this sort of information, as it provides the graduate recruitment team some context and clarity.
You could structure it as:
- Visa clarification: a short sentence or two explaining your current visa status and what it covers
- Extracurricular activities or anything else you'd like to highlight: this allows you to show a fuller picture of your experience and interests (although I'd still keep this brief)
As long as it is concise, relevant, and clearly organised, it won't look out of place - that section is designed exactly for details like this!
I hope that assists!
