Will the embassy take into consideration that my monthly income has doubled in the past 3 months when looking at my 6 months of income? I posted on the main board about this. Will they even accept a co-sponsor if my parents do this step for me? Will they approve us for a K-3 if I go thre and we marry if I we are denied because of my lack of income?

I'm afraid that the same requirements for K1 also applies to K3. You must demonstrate that you're able to support ur spouse and that he will not be a public discharge. If I were in ur shoes, I would make sure that my income is up to par otherwise u risk getting denied!

Solo,
some people here have said that their k1 petition was denied b/c k1'ers are not allowed to have co-sponsors and that k3'ers are allowed to have co-sponsors. i don't know how it is now, but back in 2004 when my husband(fiance' then) had his interview at the embassy, we used a co-sponsor and all went well. he was approved. maybe someone else in at your stage of the process can answer this question better.
