Can husband and wife submit each one entry?
Yes, If both of them have the required eligibility requirements they can submit each an entry along with the other partner's detail along with their eligible children. The Diversity visa lottery allows each eligible person to submit one entry with their name as primary applicant in the DV-2018 program. If more than one entry is submitted with a person's name as primary applicant, all the entries will be disqualified without any notifications to the applicant, regardless of who had submitted those entries.
If a person has applied for the 2015 program and was not selected as a winner in the last year program can apply for this year visa lottery draw.
If an eligible person is married then he must include his wife's detail and her digital photo in his entry. The American government allows married couples to enter each one entry if both of them meet the required entry requirements.
So the wife too can apply one entry as primary applicant if she is eligible with country, education/work experience. She must include her husband's name and digital photo in the entry.
So whoever wins both of them can enter the USA, if they proof their eligibility in the interview.
If both are selected, then the one with the highest qualification must proceed and the other one must stop with the DV processing.
They must include all the children including their previous marriage children and adopted ones, who are under 21 years of age and unmarried even if they don't intend to immigrate to the USA.
Those children who are already American PR holders or citizen are not to be included in the entries.
Polygamy marriages are not accepted by the American Government in this green card lottery program.
Those winners with high case numbers and don't have hope in being called for the interview from the DV-2016 and DV-2017 are allowed to participate in this draw.
