9 FAM 40.41 N5.2 Defining "Sponsor"
(CT:VISA-1126; 12-03-2008)
a. To qualify as a sponsor, an individual must be a natural person (not a corporation or other business entity) who:
(1) Is a citizen, national, or lawful permanent resident (LPR) of the United States (including conditional residents);
(2) Is at least 18 years of age;
(3) Filed the petition which forms the basis for the visa application (or has a substantial interest in the entity which filed the petition); and
(4) Is domiciled in any of the 50 States of the United States, the District of Columbia, or any territory or possession of the United States. (See 9 FAM 40.41 N6.)
b. If the relative petitioner does not meet the qualifying criteria to be a sponsor (for example, by being under 18 years of age or not domiciled in the United States), the visa applicant must be found ineligible for a visa under INA 212(a)(4) until such circumstance no longer exists.
Ur visa is denied under this section i have been on hold under this section as well.

Let me explain u the legal age of filing of petetion for I-129F. This is a guranted 100% correct reply based on my experience i have also faced same issue for my visa as well. There is no legal age for filing of visa petetion remember it. If some one want to marry in US he or she must be legal age as per the age requirement of the state. some states allow 16 years marriage with parental consent and some states dont allow. 18 year is a free age for marriage in usa. However incase of visa processing every visa applicant has to file affidavit of support I-864 or I-134 under section 231-A of american citizenship act therefore at the time of interview of applicant at the embassy the petetioner should be 18 years of age other wise counsellor officer will refuse visa uder section 214 of american citizenship act. 18 years age is mandatory for a sponsor to fill up I-864 thats why the visa is declined. If you need any other information feel free to ask.
