how can a foreign student get into one of the best colleges in america?

The same way as US citizens. Meet the acedemic requirements and PAY FOR IT YOURSELF.

You source out the best schools on the internet etc… and then request their catalog and application sheet. The package will give you all the info you need on meeting the college’s requirements, the forms you need to fill out for a school visa, tution fees and lots of other handy info.

Good Luck
