“If you remain in the United States beyond your authorised period of stay, you could be deported and could face a permanent ban on travelling to the United States in the future,” the US Mission in Nigeria posted via its official X handle on Monday, July 14.
This comes amid a wave of visa restrictions and immigration reforms under the administration of President Donald Trump.
Last week, the US revised its visa reciprocity policy for Nigerians, reducing the duration of non-immigrant and non-diplomatic visas to a single three-month entry.
The new policy cited concerns over visa overstays, inadequate documentation, and national security.
