Congratulations on your success! Would you kindly share your background? Bachelors uni, GPA, any research experience, GRE, TOEFL/IELTS, internships...
Btw, I would definitely try checking UT Austin for possible TA/RAships and also at ETHZ if you can survive a semester on your own budget it is quite likely that from the second semester you can get RA/TAship. My friend got to EPFL CS without sch and he started, after a semester he was assigned RAship so now he can fully fund his studies with that money. Search well and find the best for you! Ask professionals
Thank you and Good Luck!
