Some of them said they expected the announcement to coincide with the third anniversary of Monday's first explosive travel ban, which was announced on January 27, 2017, a few days after Trump took office, without warning.
So we have very strong travel restrictions and we will add some countries here. "Doubling down on it won't make any of us safer", said Farhana Khera, president of Muslim Advocates, a nonprofit civil-rights organisation.
In a statement, White House spokesman Hogan Gidley said, "The travel ban has been profoundly successful in protecting our country and raising the security baseline around the world".
Seven countries, most with Muslim majorities, are included in the existing ban which was approved and signed by Trump before two years to close USA boundaries to citizens from the former countries.
The Federal Government has described the United States President, Donald Trump's alleged travel ban plan as mere speculation.
Some countries will face bans only on some visa categories, the Wall Street Journal reported. This is evidence supplied by the department of Homeland Security in buttressing the Trump's seemingly urgent need to ban travellers from these countries from entering the United States.
The US still wants to coax Myanmar out of China's orbit, despite the Myanmar military's mass slaughter of Rohingya Muslims, Politico reported.
Aside from Nigeria, other nations in the list include Belarus, Kyrgyzstan, Myanmar, Sudan, Eretria and Tanzania.

The US Supreme Court ultimately disagreed, clearing the path for the ban's implementation in June 2018. "We urge you to wait for us to see what unfolds under the new policy, its scope, its reach, the implications, and its consequences before we react", the presidential aide said.
Somalia is among the countries included in the existing travel ban, which had been modified as a result of court challenges.
The current ban suspends immigrant and non-immigrant visas for applicants from five predominantly Muslim nations: Iran, Libya, Somalia, Syria and Yemen, as well as Venezuela and North Korea.
