Hi all,
I think the final answer should be I-134.
I was checking the DV2010 instruction and FAQ #32 states:
IF I AM SUCCESSFUL IN OBTAINING A VISA THROUGH THE DV PROGRAM, WILL THE U.S. GOVERNMENT ASSIST WITH MY AIRFARE TO THE U.S., PROVIDE ASSISTANCE TO LOCATE HOUSING AND EMPLOYMENT, PROVIDE HEALTHCARE, OR PROVIDE ANY SUBSIDIES UNTIL I AM FULLY SETTLED?
No, applicants who obtain a DV visa are not provided any type of assistance such as airfare, housing assistance, or subsidies. If you are selected to apply for a DV visa, you will be required, before you are issued a visa, to provide evidence that you will not become a public charge in the United States. This evidence may be in the form of a combination of your personal assets, an Affidavit of Support (Form I-134) from a relative or friend residing in the United States, and/or an offer of employment from an employer in the United States.
