Idaho Admin. Code r. 16.03.04.753
Sponsored legal non-citizens are lawfully admitted for permanent United States residence. A sponsor executes an I-864 affidavit of support on behalf of legal non-citizen. The income and resources of the sponsor will be deemed until the legal non-citizen becomes a naturalized citizen or until they have worked forty (40) qualifying quarters of coverage under Title II of the Social Security Act, or the sponsor dies. A qualifying quarter includes a quarter worked by the legal non-citizen's parent while the legal non-citizen was under eighteen (18) and a quarter worked by the legal non-citizen's spouse during marriage if the legal non-citizen remains married to the spouse or the spouse is deceased. Any quarter after January 1, 1997, in which a legal non-citizen received any federal means-tested benefit is not counted as a qualifying quarter.
