Black belts going to Okinawa 2023

I'm Lucas' grandmother and legal guardian. Lucas has Autism but does not let this hold him back. Lucas earned his black belt in both karate empty hands and kobudo at nine years old. At this time Lucas is invited to join the black belts of Axsom Martial Arts going to train in Okinawa in April, 2023. Okinawa is the home of Lucas' style of karate, Shorin-ryu Shorinkan, so it's exciting to be included and meet some of the founding Sensei's. We would be most appreciative of any and all help to assist Lucas in making this trip accessible. My husband, George, is a disabled veteran presently healing from cancer surgery and treatments, therefore the reason for our limit of funds at this time. Thanks in advance.
