I appreciate all the feedback. I'll try to be clear with a complicated issue.
My income is only SS and VA Disability, which combined, does not meet the 125% guideline. I would like to get a part time job to make up the difference, but my life circumstances at this time makes it difficult to have consistent employment.
The only asset I have is a home I own, no mortgage. The appraised value would be well above the required 3x amount for the difference in income. I am putting it up for sale since I relocated from another state to my sister's residence, temporarily, for the purpose of being closer to family. With the proceeds of my current house, eventually, I intend to buy another one near my sister.
From my understanding of what I've read here on VJ, and elsewhere, it seems like using assets to make up the difference is a shot in the dark. So, I had asked my sister if she would be willing to help. However, I don't understand which form she should use, I-864 or I-864A. She owns her home, and her only income is SS survivor benefit, which is above the 125% guideline. There is no other joint sponsor available.
If she would not be a good candidate as a sponsor, or if using my assets may not be sufficient, then I will need to reevaluate if I should continue in the visa process. It's too stressful, time consuming and costly without some kind of hope that we have a reasonable chance of success.
