Except that immigrants do not need sponsors that ensure they will not be a burden on the Republic. Far from it ---- a sponsor only needs to be 125% over the national poverty level and the sponsor's income is counted in with their immigrant's income which could be $0 a year when determining eligibility for government programs like SSI and Medicaid. A sponsor does not need to ever contribute a dime toward the upkeep of their immigrant.
According to the guidance, the question on the I-864 regarding the use of means-tested benefits by a sponsor or a member of the household in the past three years ensures that such benefits are not counted as income on the form. Sponsors should not be disqualified for responding that they have used means-tested benefits. The guidance states that sponsors may count earned benefits as income, including those derived from Social Security retirement, Unemployment Compensation, and Workers Compensation. Notably, the U.S. State Dept. does not allow the latter two benefits to be counted as income....
A sponsors spouse may choose to complete Form I-864A (Contract Between Sponsor and Household Member) if he or she qualifies as a household member and wishes to have his or her income counted towards meeting the 125 percent-of-poverty requirement. However, since the spouse is not required to complete this form, the sponsor may be limited to using his or her own income and assets in meeting this requirement. Where a sponsors spouse qualifies as a household member and is the sponsored immigrant, he or she should not complete Form I-864A. However, if the spouse is the sponsored immigrant but there are also immigrant children of the spouse listed on the affidavit of support, the spouse must complete the I-864A.
The guidance states that a sponsored immigrants income may be used toward meeting the sponsors income requirement if the immigrant has been living in the sponsors residence for at least six months prior to the adjustment interview. The sponsored immigrant should not complete Form I-864A in this case because it is presumed that he or she will support him or herself. However, if there is a spouse and/or child immigrating with the sponsored immigrant, the sponsored immigrant must complete Form I-864A in order to have his or her income counted.
A sponsored immigrants assets may be counted if a sponsors income and assets are insufficient by themselves. In this case, the net value of the immigrants assets are added to those of the sponsor. The immigrant does not need to complete form I-864A to have the assets counted.....
