Thanks for the help?? kinda silly to talk about the Cr1.. I expected to get hit with "why didn't you apply for renewal 5 months ago?"
Its a bit late to talk about the benefits of a CR1 vs K1. about 4 years late!!.. There really wasn't a choice for us as we didn't decide to get married until I returned in Jan 2020 as covid hit. So K1 made sense for us.. Yes I wished I had married her on my July 1019 trip.
Luckily we are not in a rush, at least I hope. We hope to get her driving license before this combo expires.
