I was reading that some former national players are speaking up about changing the law so grand children of TT nationals can get citizenship. Apparently there's a base of players who are available (I haven't seen or heard of any players).
I'll tell you this, that TT government will never change the law to accommodate a football team. That law is very protectionist and outdated to say the least.
If the government decides to revise that law, they will put in a clause that will only grant citizenship for national interest. Maybe that's the way to go.
