What Ivy League Colleges Accept Transfer Students?

I want to start off by going to a community college for a year or two then transferring into a four year University like UCSD or NYU. But my dream colleges are Cornell, Brown, and Columbia University. I definitely plan to retake my SATs after I graduate high school in hopes of scoring above a 2000. I plan to study hard and have a private tutor and also work on my own. I’ve heard amazing stories of people getting into Yale, Stanford, and Cornell by using this method. I definitely plan to be in multiple extracurricular activity’s, do loads of community service, and learn two languages by the time I finish a four year University.I basically want to do anything and everything that will help my chances for the Ivy League.
Finally the questions:
What Ivy League Colleges take transfer students from Community Colleges or University ?
What will better my chances of making it ?
What are my chances of making it if I stick to the regimen ?
Have any of you made it by following this method or one similar to it ?
Please and Thank You! I’m extremely serious and passionate about this.
