Hello & Welcome,....
in 2008 my wife & I took second honeymoon to Honolulu, I was surprised by noticing two firearms ranges in the Waikiki Beach area the appeared to caterer to foreign nationals, for first time firearm training, it was an expensive endeavor.
I, recommend that you "google", firearm trainng - Waikiki, and see what develops and contact those listed to see if they have references from your homeland.
Having lived in Seattle, WA, there are some training facilities there but not certain what is available for visitior from outside the USA??
Maybe contact the moderator "Pax" of this forum, she is from that area and MIGHT be able to assist.
Welcome, again and Good luck!
