5-year US Visa for Nigerian passports.
The US embassy in Nigeria has increased US visas from 2 years to 5 years for visit and business visas. So if you apply for a US visa now, you will get a 5-year visa instead of 2 years. Great News! The visa fee remains the same.
The visa validity extension allows Nigerians to use the visa for 5 years to make short trips to the United States for tourism or business purposes before having to renew their visa. The visa application fee, currently USD160, will not increase as a result of the increased visa validity.
