Form: I-864 AFFIDAVIT OF SUPPORT UNDER SECTION 213A OF THE ACT. No (Cost for Filing) (To show that the applying immigrant has enough financial support to live without concern of becoming reliant on U.S. government welfare.) NOTE: You must have this prepared properly and ready for her to file before the time of the interview!.

A final note about the I-864 and the accompanying documents. To many American men this is the scariest of all the forms. The fact that both the Affidavit of support and the accompanying documents must be turned in prior to, or at the time of the interview provides the fiancé or spouse with a chance to make copies of information and financial records and history that would make a divorce attorney scream with delight (or in extreme agony) depending upon which side he is on. We have actually been called upon to be there at the day of submission of these documents so that they were filed on time, but so that the fiancée lacked time to copy all the documents!
