TIP team player statues question

http://lol.gamepedia.com/Team_Impulse

xiaoweixiao is foreign exempted.. rush is ... Korean impact is ... Korean Apollo is ... NA adrian is .. NA

Gate is ... what?
http://lol.esportspedia.com/wiki/Vortex

because on the TIP wiki thing it says Gate is NA on the vortex wiki it says Gate is chineese.

Rule that clarifies exempt and non exempt people started in sept 5, 2015 sept 26, 2014 Final Five was created .. and Gate was on that.. and he joined Oct 15, 2014

Rush joined LMQ in November 2014.. is he exempt? because it doesnt read like he is based on time lines. impact came to NA in Jan 2015

so.. getting some info from this article: http://na.lolesports.com/articles/interregional-movement-and-expansion-tournament

i am still confused but this is what i see..

Rush - non-resident impact - non-resident xiaoweixiao - exempt apollo - Resident Gate - non-resident

Did TIP just play an illegal roster on july 19,2015?
