You will need to find a co-sponsor. It can be any U.S. citizen or permanent resident at least 18 years of age living in the U.S. That person will need to meet the income requirements for their household size counting their spouse, dependents, and the sponsored immigrant. The government has 90 days to give him the employment authorization once everything is filed. At that point, if he is working at the time of the interview, then he can bring an updated affidavit of support and evidence of his income, and you can attempt to withdraw the first affidavit of support and substitute the new one. It's a bit tricky, and sometimes they officer doesn't want to do it. However, you will need to have a co-sponsor, so the application won't be rejected initially.
