I lived in Puerto Rico when my oldest son was trying to find a place to play college football stateside.
There are two separate challenges for the Puerto Rico high school athlete wanting to play college sports on the mainland: the first is convincing stateside colleges of your English and academic proficiency; the second is getting your sports ability evaluated. Both challenges require extra initiative on your part.
Regarding the first challenge, you must understand that stateside schools will assume your English and academics are not up to snuff until you prove otherwise. I suspect this challenge is one reason such a high percentage of PR's top prospects go pro instead of to college.
Regarding the second challenge, at least with baseball, people already realize the sport is played at a high level on the island. Football was a much harder sell.
The advice already given to re-trace the paths others took seems right. If your measurables are good and you can afford the cost, a stateside Perfect Game showcase could be a good investment for you.
Carlos Baerga used to own a winter league team in Bayamon near where I lived. He was very gracious to the military families, supporting events on base and giving free admission to games.
Best wishes,
