There is a K-1 flowchart at K1 Flowchart Visuals : British Expat Wiki. However, some items are now out of date.

I've recreated this and attached. Could someone proof check it please? If it's ok I'll update the wiki with it and the source file for the future.

This is terrific! The only alteration I'd make is remove the $$ amount for the I-129F filing fee. That'll make it useful into the future if/when the fees change. Great job!

Thank you, Tom, for your assistance. If you want, you can always have a look at the other US marriage-based documents on the wiki. As they might be out of date as well.

Thanks! Will make the amendments and upload tomorrow when I'm on the computer.

Good work Tom, I planned on updating it after I got my K1 but predictably forgot, good on you for being pro-active!
