I really appreciate your advice! I'll definitely have a conversation with her about switching to CR-1.
Regarding the CR-1 Visa, Is it possible for us to marry when she's out of the country and apply for CR-1 right after?
I have mentioned CR-1 with her the other day, but she was told by somebody that we have to be married for 2 years to be eligible, thus that was the other reason we stayed with K1 as well.
