I put N/A (K-1 visa process for permanent residence) .. Most other people on this site put the same, and it goes over fine. This form is sort of an "all-purpose" document, it's used for several kinds of visas. But I've heard of others putting "I intend to marry (so and so) within 90 days of their entry into the US" and that went over fine too.
DavidsPrincess got a reaction from Curlies in I-134 Q11. I intend/do not intend to make specific contributions to the support of the person(s) named in item 3
