I'm about filling the ds 156 form for lagos consulate for k3, can some tell me what to indicate on question 26,27,28 and 32 and 33. i will really appreciate it alot.

You may want to look at the example form under K1 visa the answers are similar.

26 Permanently
27 Relocation to USA to be with spouse
28 Myself
32 If you intend to work check yes and write "with work authorization, employer unknown"
33 If you intend to go to a college check yes and "College to be decided"
