Efia, it looks like your husband got the instructions for getting a CR-1/IR-1 visa and not the K-3 visa.
From the US DOS for CR-1/IR-1 visa:
QUOTE
Application for Immigrant Visa and Alien Registration, Form DS-230, both Part I and Part II
From the US DOS for K-3 visa:
QUOTE
Two copies of form DS-156, Nonimmigrant Visa Application
One DS-156K, Nonimmigrant Fiancé(e) Visa Application form
I would suggest that you call the embassy ASAP and make sure you are clear what visa you are applying for.
