I have to agree with everyone on this post that because you’re looking to transfer into elite universities your chances are almost none.
Why do I say this? Well the first and worst issue is that you need 100% financial aid. That’s hard to come by at most universities, and yet you expect the most elite, competitive, and most applied to universities, in the world, to accept you. I am assuming that you already applied to these universities, in your first attempt, to come to the US as a student, and you were rejected; am I correct?
Another issue is that these classes at these elite universities are small. There aren’t enough seats for the hundreds of thousands of students that want to attend these schools. If there is a transfer that is accepted, it’s usually a US soldier or an Olympian, or someone that has made international headlines. These seats are finite and you have to hope and wait that someone transfers out in order to make room for another seat. That rarely ever happens.
Your major is computer science. This is a big issue because a number of US schools are impacted and don’t have spaces for computer science majors. The elite universities that you’ve chosen are not known as the best for computer software studies.
Because you are international, in need of full funding, and have chosen one of the most impacted majors, and you are already receiving an education in computer science, I don’t see your transfer applications as being successful.
It is well known that transfer students just don’t receive the same kind of funding as entering freshmen. The schools hold their funding to entice new freshmen, recruited athletes and underrepresented populations.
If you were to be considered an Ivy League-caliber student, then you would have by now:
created your own hackathons for UT,
drawn interest from regional schools participants, college internships corporate businesses, etc.
obtained funding, supplies and programs from local and national sponsors,
added these events to your university calendars.
My kid and a group of his friends did this. But it takes time, planning and a lot of dedication. You have to develop relationships with students, professors and local businesses. Work at the university that loved you, and love it back.
Edited to add: How do you plan on getting loans? You can’t get loans from any US Bank, loan company, or federal student loans, because you don’t qualify for funding as an international student. Any bank would ask for collateral. If you’re low-income, you wouldn’t qualify for loans.
