Hi Kambria! Thanks for writing in.
You can find more information by going to the Pascua Yaqui tribe’s official website: https://www.pascuayaqui-nsn.gov/.
In terms of what percentage you need to be to enroll, it looks like ¼ is the minimum quantum required. That means that either one of your parents would need to be at least ½ or both parents are at least a ¼. You can find out more about their enrollment process here: https://www.pascuayaqui-nsn.gov/index.php/enrollment-home.
Thanks for writing in and best of luck!
