There are many exchange students looking for host families before the school year begins. Find a loophole where your schools families who's son/daughter participate in soccer accept being host parents. Have them cherry pick the soccer players out of that exchange pool and you got yourself your own little international soccer team for the high school season.
Is it a wild suggestion? Perhaps.
Does it give your hometown team an unfair competitive advantage? Perhaps.
Is it legal? As long as the host parents are willing to put up with a 14-18 year old foreign student for 10 months, absolutely!
