Hi, just joined and hoping to get some answers about my query.

I have a Japanese passport and I would need to revoke if I want to do anything that I plan to do (such as MEXT or JET). The annoying thing is that it runs out next summer, and I don't plan to use until then it or renew it.

Does anyone know how long it takes to revoke it, and what I need to do? I don't really want to go to London until I know what I'm doing. Plus I don't want to revoke it if I know it will take some time, which would mean I'd be too late for applying to stuff. I did email the embassy but I didn't get a reply and I don't want to try again so soon!

Any help would be great.
