The US U-20 Men's National Team will be in Costa Rica in February for the 2017 CONCACAF U-20 Championship. Sensibly, the U-20s are in Costa Rica at the moment for a training camp, which includes a couple of friendlies against the Costa Rican U-20 national team.
The draw for the CONCACAF U-20 tournament makes it unlikely the US and Costa Rica will face each other in the competition, unless both teams make the final. But playing the host team of a major international tournament on its own soil (CONCACAF's representatives at the 2017 U-20 World Cup will come out of the competition in Costa Rica) is never bad preparation.
