US Immigration from Japan

Things didn't work between my ex and I, and we are now officially divorced in Japan. As you can probably guess, we both would like to withdraw our USCIS visa application, but we aren't sure on how to go about doing so right now. Do I necessarily need to mail them a letter of withdrawal?

If we don't respond to anything they send in the future, will they eventually just close our case? Do I send it to the service center our visa was sent to? Are the service centers receiving mail right now? Any and all help or a link to another thread would help tremendously, thanks.

1. I plan to put in her high school info. Does she need a copy of her diploma?

2. She attended college for about a week, if that. Is it necessary to put that info in there?

Thank you, everyone!

Is there a way to set browsing preferences so that it jumps to first unread post in a thread when you click a thread title in the forum list?

I know there's the "Unread Content" option that shows you basically everything - which is not what I'm interested in. Sorry if there's an obvious solution that I haven't found.

When entering your name (first and last), it also asks for aliases, maiden names, etc. Is it necessary to include nicknames or shortened names? Such as "Daniel" become "Dan" and anything like that. Thanks!
