The 19-year-old RBNY Academy grad is joined by former Red Bull Andrew Jean-Baptiste (recently signed up to play his club soccer in Sweden) and Shelson Dorleans, a goalkeeper with Academy ties. Dorleans made one appearance for RBNY's U-23 team in PDL this season.
Haiti faces two World Cup qualifiers in early September: at home against Costa Rica on September 2; away to play Jamaica on September 6.
Les Grenadiers currently have one point from four games played in Group B of the penultimate round of CONCACAF qualifying for the 2018 World Cup. Should they win both their remaining matches, they have a shot at squeaking into the Hexagonal tournament that will decide the region's representative in Russia - but the games played to date suggest that is an unlikely outcome.
As such, it is time for Haiti to look to the future. The 33-player squad could yet simply be trimmed to a 23-man roster of more-or-less familiar first-teamers, but it might be reasonably expected that head coach Patrice Neveu will take the opportunity to test (and cap-tie) a few of the emerging prospects in the player pool.
If Etienne makes the cut, and makes the field, he will have effectively committed himself to Haiti's cause - as he will have appeared in a senior-team competitive international. He is also eligible to play for the USA, but appears to have been mostly ignored by the US national team set-up, despite a growing reputation for his club and a lengthy courtship by the Haitian federation.
