2) from where we get the ds 156 form?

3) in form ds 230 part 1 they need information about my spouse but i m applying for k1 fiance visa, so does she put my name (i am her fiance), or leave it blank?

4) now after getting p3 what exact documents i should submit at vsf office?

5) the form i-134,affidavit of support should be filled up by my fiance residing in US then what the sent it to me ,what i should do with that?
