point well taken. i am a little tired tonight and now see that i did not wrote what i was thinking. why is there a different affidavit for aos and a different one with the petition. that was where i was going and somehow got way off track. sorry.
The I-134 is used only by the consulate for Non-Immigrant visas, like the K-Visas, visitor, work, business, student, etc. The Non-immigrant has a limited period of stay, not like an immigrant, that has an indefinite period of stay.
The I-864 is a binding Affidavit of Support used to lock in the sponsor of an immigrant that will be issued a green card, the 2 affidavits have different purposes. The I-864 is the sponsor's guarentee that the sponsored immigrant wont become a charge of the state.
