I just picked up my interview package from the Embassy in Costa Rica. Since I am using a cosponsor who owns his own business, they specifically and clearly require from me and my cosponsor the form I-864 not form I-134. I asked about the I-134 and they said that the form I-864 is what this embassy requires from me at the interview. I am sure we are not interviewing for th I130 because I have not received or sent any further forms for the I130.
I am not posting this to argue FAM rules but to only inform y'all of my own experience at the conof in Costa Rica. For anyone who has a similar situation, I would strongly suggest contacting the embassy at which your interview will take place.
Good luck and God Bless,
Chris
