I-134 has conflicting information in it. In the form it says:
That this affidavit is made by me for the purpose of assuring the United States Government that the person(s) named in item 3 will not become a public charge in the United States.
That I am willing and able to receive, maintain and support the person(s) named in item 3. That I am ready and willing to
deposit a bond, if necessary, to guarantee that such person(s) will not become a public charge during his or her stay in the
United States, or to guarantee that the above named person(s) will maintain his or her nonimmigrant status, if admitted
temporarily and will depart prior to the expiration of his or her authorized stay in the United States.
That I understand this affidavit will be binding upon me for a period of three (3) years after entry of the person(s) named
in item 3 and that the information and documentation provided by me may be made available to the Secretary of Health
and Human Services and the Secretary of Agriculture, who may make it available to a public assistance agency.
However, the instructions say that a separate form is required for each person. Someone may take a more conservative view and submit 2 applications. I got lucky I guess.
