It is required that each applicant be native/born of one of the qualifying countries to fulfill the eligibility criteria of applying for an immigration visa to the U.S. Here, a qualifying country is basically a country that is included in the list of eligible countries for this program per year. Also, keep in mind that if the applicant is not from one of the qualifying countries but his/her spouse was born in one of the qualifying countries then the applicant will be able to claim the country of his/her spouse under the condition that the visas will be issued to both the applicants and they will have the option to live and reside in the United States. Moreover, if the applicant is not born in a qualifying country but his/her parents are, the applicant, in this case, may claim the right to enter by the nativity of the country of origin of his/her parents.
