I graduated from UTA 2 and 1/2 yrs ago and never bought health insurance from UTA. You can get cheap health insurance for $30-$40 a month from https://www.isoa.org/ which I used during my time at UTA. It is sad to hear that now they have come up with new regulations regarding the health insurance. I think  your best bet would be to print the plan brochure  from isoa and talk to the international advisor, or enter the info from the brochure and see if it qualifies you for the waiver.
