USA Visa Lottery. Education Requirements for the Nigeria based Applicants.

USA visa lottery requires Nigerian people to have the following educational requirements. Many of the bogus agents can tell you that you may qualify under the work experience. it is very rare to qualify from the Nigeria for the Green card lottery under the work experience. We suggest you don't apply for the DV Lottery if you don't have the educational qualification.

Your Educational Qualification according to the US Embassy in the Nigeria as follows.

To qualify for the DV program, you must have the equivalent of a U.S. high school diploma. In Nigeria, this means you must have 5 scores of “6” or higher in 5 different subjects on the WAEC, SSCE, NECO, or NABTEB certified exams. You may also qualify with a BSC degree, HND, or OND from an accredited university or polytechnic institution.

Do all subjects on WAEC or NECO count for the purposes of the DV?
No. To qualify, the subjects must be academic subjects such as English, biology, or math. Trade subjects, for example plumbing or garment making, do not count for the program.

Can I combine scores from different exams?
You can. Any combination of exams from different years can be combined. For example, you can use 3 passing scores from a WAEC exam from 2002 and 2 passing scores from a NECO exam in 2003 that will qualify for the program. However, each of the 5 passing scores MUST be in different subjects.

What else should I bring to the interview to demonstrate my educational qualifications?
At the time of interview, you should bring the official exam certificate or a computer printout with an unused scratch card. If you have a higher educational qualification, such as a
National Diploma, Higher National Diploma, or a University degree, you should bring the appropriate certificate. And transcripts, though not required, are very helpful. National youth service completion certificates also - not required, but helpful if you have them.
Please Do NOT bring fake certificates (even if they happen to show your real scores!)—you will be disqualified.
Please also Do NOT bring scores from exams for which you did not sit yourself—you will be disqualified.
