If you want something in the realm of business, but also an OPT-eligible STEM degree, there are a number of options. You’ve probably looked this up already, but both the Business Data Analytics major that you mentioned, and the Computer Information Systems major in the business school, as well as Econ, are STEM-designated.
I don’t know whether switching into an engineering major is possible, but if it is, you might also look at Industrial Engineering, which sits at the intersection of engineering and business. This could be a highly-employable STEM degree, if it interests you and if it’s available to you: https://degrees.apps.asu.edu/major-map/ASU00/ESIEEBSE/null/ALL/2022
There’s no particular need to do a double major for which both majors are STEM (like Econ + Business Data Analytics that you mentioned). But if there’s a particular major you really want, that is not STEM, combining it with a STEM major could be smart. (One extremely highly-regarded business major at ASU, that is not STEM-designated, is Supply Chain Management. This can be a great field for someone with an international perspective.)
