Rightly as you said, the US embassy in Ghana is not allowing new immigrants to board flights which is unfair because I read online all the time about people who travelled to activate their status even when the virus was at its peak and ban in place.
So like I mentioned, there is an alternative route that those with visas can use to activate their status.
Think about winners from EU region, if you have been following britsimonsays recently, the way out is to travel out of the EU region to another country, spend 14 days then travel to US to activate their status.
Why will you go through this year long process, use your time, energy and resources to get the visa then sit down for the opportunity to slip through your fingers.
Lastly, do you think the US embassy in Ghana will resissue visas, when they are stopping people with visas from travelling.
I stand to be corrected.
