Affidavit of Support for DV Lottery Winners.
When the DV winners are going for the interview, they must provide Affidavit of support for them and each of their dependants to the interviewing consular officer. This is to prevent them from being as public charge while they stay in the USA legally.
So the affidavit of support is considered as very important document for the dv winners. The American Government is strictly enforcing this rule as, no affidavit of support (or have enough wealth) the immigrant visas will not be issued under the diversity visa lottery program.
Winners in the USA too must provide this affidavit of support. Otherwise they will not be allowed to change their current status to LPR status. Usually many petitioners agree to provide the required I-134 form. and at the last minute they used to back away from their promise. It is better to keep one or two more petitioners in the standby list to support you in case, any of them don't support.
Affidavit of support is equal to sponsor documents that used in in many parts of the world and now it is must for all the DV Lottery winners who want to have their visa under this program each year. Its (Green card lottery) instruction clearly states that all the winners must provided one affidavit of support through the I-134 form. on the day of the interview. The petitioner must be an American citizen or must be an American LPR holder. It can be a relative or friend of yours. Others can't provide this Affidavit of support to the winner.
Also the petitioner must provide required relevant official papers along with his financial report papers to the winner before the interview.
On the day of the interview applicants must present these documents to the interviewing consular officer along with other necessary documents. This requirement will apply to those winners in the America too when they want to change their current US status to the U.S LPR status, through USCIS office.
Affidavit of support must be provided through the I-134 form. While some consular offices want them in I-864 form from the green card lottery winners to issue the Immigrant visas. Some time the agreed petitioner may change his mind and don't want to support you, so there is no problem in changing with a new petitioner's name and information on the day of the green card lottery interview.
Those people, who don't have a petitioner to provide an affidavit of support for them, can proof that they have on arrival job arrangements and enough funds to meet their needs in the USA. In this case, the consular officer will decide on whether to issue the required immigrant visa for the green card lottery winner or reject the visa depending on the funds and the available job.
American Government had introduced this rule as it had found out that many winners who had arrived in the USA in the early years without proper support in the USA, did suffered without proper Jobs, lodging and food. Because of this they had introduced the Affidavit of Support requirement for the current DV Lottery winners to be issued with the required visas.
Some of the petitioners may not like to give you the affidavit of support and their financial report to you. In this case they may send the scanned copy to the relevant consular office through email just before your interview date.
