you can. There are several government scholarship for undergraduates. Check Turkiye Burslari, Kazakhstan government scholarship, Burnei Dar es Selam govt scholarship, KAIST scholarship, CSC scholarship, MEXT Japanese scholarship, etc. There are also universities that give full scholarships like US universities who give 100% financial aid to students (you can google them). And in Canada there is Alberta university scholarships and University of Toronto Lester B pearson scholarship, just to mention some. If you dig more you’ll find more and you can apply. However, it’s not easy to get undergrad scholarships compared to graduate school scholarships. The applicants for undergrads are many and the opportunities are not that much, and they’re very competitive. So it’s okay if you get a degree in Ethiopia first. Make sure you get a good GPA, take part in extracurricular activities and stuff and you’ll be able to apply to many graduate scholarships. Goodluck!
