J'adore mon alger

So were going to go through with the CR-1 how do i get that visa application for CR-1 to fill it out?. We have our i-130 filled out and have most of the documents ready to go 

My husband came here on a 2 year multiple entry visa hes been here since November, we got married February 4th in the USA . We didnt meet and decide to get married till his second time here. His Visa expired Dec 8th but his 6th month extension ends on may 12th. His Father is in the hospital and maybe the last time for him to see him (my husband still in america) his father is in algeria. He wants to leave before filing AOS. I want to know whats the best avenue for us since we havent filed anything. Would him going back and me filing I-130 and K3 the best way?. And how do i go about doing that?. Please any guidance would be greatly appriciated.
