Citizens of Nigeria and 35 other countries face imminent visa ban by the United States.

President Donald Trump’s administration is considering the ban, which would be a significant expansion of the travel ban announced by his administration early this month.

According to The Washington Post, the list of countries was contained in a State Department memo.

At least 25 African countries are included in the proposed ban.

In total, there are 25 African nations facing visa bans or other restrictions.

Corruption in governance and unreliable identity documents are the major reasons for the proposed ban.

The memo, which was signed by Secretary of State Marco Rubio, revealed that the governments of listed countries have a 60-day ultimatum, to meet new benchmarks and requirements established by the State Department.

It set a deadline of 8am on Wednesday for them to provide an initial action plan for meeting the requirements.

The memo noted that some countries had “no competent or cooperative central government authority to produce reliable identity documents or other civil documents,” or they suffered from “widespread government fraud.”

Others had large numbers of citizens who overstayed their visas in the United States.

The countries facing scrutiny in the memo included: Angola; Antigua and Barbuda; Benin; Bhutan; Burkina Faso; Cabo Verde; Cambodia; Cameroon; Democratic Republic of Congo; Djibouti; Dominica; Ethiopia; Egypt; Gabon; Gambia; Ghana; Ivory Coast; Kyrgyzstan; Liberia; Malawi; Mauritania; Niger; Nigeria; Saint Kitts and Nevis; Saint Lucia; Sao Tome and Principe; Senegal; South Sudan; Syria; Tanzania; Tonga; Tuvalu; Uganda; Vanuatu; Zambia; and Zimbabwe.
