You can’t apply as a high school student because you’re not one. Purdue might not accept you if you violated the terms of the gap year agreement, so you’d likely have to apply to a new list of schools. When you apply to US colleges you have to include the transcripts from your current school in your application. But no matter where you go, even if you leave your record behind, your habits and ethics will follow you. If you cheat in the US you can be expelled, sent home, and not permitted to return. If you lie on your application and are caught, you can be expelled, sent home, and not permitted to return. Admission for Asian students is very competitive, so your current classmates, faculty, and advisors all have something to gain by exposing you. Whether it’s a possible admission for themselves or one of their students doesn’t matter, and it only takes one. If the ethics don’t bother you the risk of being outed should.
But if finances are such an issue that a $5k tuition in your home country is unaffordable, how would you be able to afford an education in the US? Travel expenses and insurance will cost more than that. And there’s far less money to go around this year.
Your best option is probably to get an (honest) degree in your country, take the time to get better acquainted with ethics, and apply to US colleges for grad school.
