So, I guess this is a dumb question, which I am hoping someone can answer. But, I keep seeing two scenarios constantly going on: 1) On TRN, a player who is from a foreign country plays sectionals and zonals and regionals. 2) On TRN, a player who says they are from here and plays sectionals and zonals here , but plays ITFs with another country's name for easier access to the ITF's in this country. My question is are sectionals and zonals and even regionals open to juniors from other countries? ( excluding Canada from this discussion). Thanks.
