I-134, affadavit of support and co-sponsor questions

[Goldfinger 4]

I'm preparing for my interview, when the time comes, and was wondering a few things about the Affadavit of Support.

#1 - My fiance's mother (my fiance is the U.S. Citizen) is going to be a co-sponsor or joint-sponsor or whatever. What do I do in this case? Do I just have her fill out an entire seperate I-134? What evidence should I collect from her? Is there some way to establish or represent that she is, in fact, a co-sponsor?

#2 - My fiance is currently jobless, as she's been with me in my country for some time. She is, however, looking for jobs and I am pretty well certain she's going to find one pretty quick. What do I do in this case though, because she doesn't really have an annual income, and won't even after she gets the job, inasmuch as she will only have a few paystubs. Do I take these with me? Should I multiply it out to predict what her annual income will be?

#3 - I thought that I read somewhere that I can co-sponsor myself as well. Everyone says my savings and financial standings have no bearing on the process, but I've read otherwise. Can anyone help me with this?

BTW, we received our NOA2 a week ago, just to let you know how far long we are into this.

Edit* We are going to live at her mom's house, so I think that factors in as well, seeing as not having to pay rent constitutes "income" from what I've read.

Also, I have an uncle who owns a business in Colorado. Would it be worth my while to get one from him?
