Affidavit of Support
Form I-864, Affidavit of Support under Section 213A of the INA, is a contract an individual signs agreeing to use their financial resources to support the intending immigrant named on the affidavit. The individual who signs the affidavit of support becomes the sponsor once the intending immigrant becomes a lawful permanent resident. The sponsor is usually the petitioner who filed an immigrant petition on behalf of the intending immigrant.
Thanks to Leila for doing a wonderful follow upon RFE for the EAD. I got my EAD approved very soon after an RFE was issued.
