Nigerians brace yourself - countries with laws that target gay people will have their citizens in a situation where it will be very difficult for them to get immigration visa. As you know, Nigeria has a law that specifically targets gay people:

The executive order is expected to include a list of acts that would disqualify an individual from entering the U.S., two sources briefed on the language said.
