I have a volunteer opportunity this upcoming summer, though that would require me to travel overseas to a relatively Covid-contained country. Is it wise to mention this opportunity and say that I plan to go there if the Covid-situation becomes safe and appropriate by then? Thanks!
I think schools are more interested in what a you’ve done, not what you might do well after the application/acceptance process.
If you were selected through some competitive process, or have prior involvement with an organization sponsoring the trip, include those things.
