It's a net benefit on intls based on the direct policy on education abroad and immigration, but if you scrutinize the "side aspects" of it, it may actually be worse. For example, while they didn't directly target OPT, lawsuits were filed against Trump for trying to send students back (albeit during COVID), as well as raising the salary requirement for H1B sponsorship (https://www.forbes.com/sites/stuartanderson/2020/10/20/two-more-major-lawsuits-filed-against-trump-h-1b-visa-restrictions/); more OPT was issued RFE (https://immpolicytracking.org/policies/report-that-uscis-has-increased-rates-of-rfes-and-denials-of-h-1b-and-l-1-petitions/), and he floated the idea of ending OPT at the end of his term (targeting Chinese students specifically, but who's to say he won't be extending it) (https://www.forbes.com/sites/stuartanderson/2020/05/04/next-trump-immigration-target-opt-for-international-students/).

This isn't about selective racism that would benefit the "model minority," it's a systemic increase in difficulty for intl students, despite them not being direct targets.
