1. That form is not an I-134 which is the correct affidavit required in this case. Plus the documents being submitted in support of the affidavit needs to be current.
2. I can't quote a figure, one's annual is usually given more consideration. My suggestion is to find someone to fill out the affidavit of support for you.
What should the income of the person filing the I-134 be? Also, the person filling the form out would have to mail it to USCIS and go through that process. How long does this process take? Will he receive his forms back so he can give them to me so I can present them to the interviewer?
If you have real estate, should you bring the documents showing how much tax you're paying for that property and how much it's worth?
As a side note, I have been in the U.S. for close to 14 years now, a majority of that time I was on an F2 visa. Do you think they will ask me how I will support myself during my stay, considering I've been here for a while?
