Prise en charge nécessaire après avoir gagné à la loterie DV ?

Pas necessairement. Si tu as un contrat d'embauche ferme ou suffisemment de fonds, tu peux te passer d'un sponsor. Cela reste quand meme a l'appreciation de l'officier consulaire.

Affidavit of support is a necessary requirement for the DV Lottery winner and his/her dependants, according to the DV lottery instruction. This is to prevent the dv lottery winner from becoming a public charge. Sponsor/Petitioner must be an American citizen or a LPR (lawful permanent resident) holder. He must have enough income to prove that he can sign the affidavit of support form on behalf of the diversity visa winner. The sponsor must use the affidavit of support form and must be sworn in front of authorized officials as described in the advice. The petitioner must have enough income or financial resources in the USA. There is no filling fee for the form. Duly filled and signed affidavit of support form must be provided by the Diversity Visa lottery winner to the Consulate officer on the day of his/her interview.

The Sponsor/Petitioner may need the following things:
- Proof of citizenship or status in the United States
- Notarized affidavit of support (I-134 Form)
- Federal Income tax return (1040 Form) for the most recent tax year
- W-2 Form for the most recent tax year

It is better to contact your Embassy or Consulate in your country and ask them about their requirements regarding this sponsorship. Failure to meet this Sponsorship requirement may result in the refusal of the winner's visa.

If you don't have a petitioner/sponsor then you must proof to the interviewing consular officer that you have enough funds to take with you to the U.S.A .The consular officer will decide whether you can be issued with the visa or not, after himself reviewing your financial report which you can provide on the day of the interview. The consular officer's decision will be the final.
