UPDATE: Stefan Frei broke the news on Twitter: The U.S. player pool just increased by one.
Thank you all for the love and support! I'm proud to finally be an American and will do everything to make my fellow citizens proud #USA— Stefan Frei (@Stefan24Frei) June 13, 2017
Sounders goalkeeper, Swiss native and USMNT hopeful Stefan Frei is taking his U.S. citizenship test tomorrow— Matt Pentz (@mattpentz) June 12, 2017
Should the Switzerland-born Frei pass the test, he would then have to have his national team eligibility changed by FIFA to the US from Switzerland before he could play for the Yanks in official competition. Frei represented Switzerland once on the youth level before moving to California as a teen.
The 31-year-old was called to the USMNT’s January training camp this year, but had to depart early after suffering an ankle sprain less than a week into proceedings. Now in his ninth year in MLS, Frei has started all 15 of the Sounders’ regular season matches this season, recording five shutouts and 41 saves.
