I know Greensboro Invitational in NC is one. They listed it on their fb at the end of July. The meet is February 6-8. A quick google search shows that Buckeye, Star Struck Invitational, WOGA, Magical Classic (FL), and Brestyan Invitational are others. I would think the gymnastics meet being held in conjunction with the Liukin Cup in TX will also be a qualifier. I couldn't find any other reports on the remainder meets.
We made our own potential list and I have 27 but some gyms leave the logo up even after they no longer run the meet so it's hard to confirm. There a few new ones to (Starstruck in NJ) but we need confirmation to get our meet schedule locked in so waiting on official list and # of Jr/Srs from each event.
