If he is in Yesodei Yeshurun, then they have a beis midrash Ohr Hachaim. Many of the bochrim will go to Lander College or Queens College at night and go to Eretz Yisroel for a year or two when they graduate.
ToMo is another great yeshiva that some of the bochrim go to. ToMo has a college arrangement with Execelsior College (I don’t know the details) and others will go back to America to Landers, Ner Yisroel, or Queens College.
Another place some bochrim go to (albeit not many) is Kerem B’Yavneh, also a great yeshiva. The yeshiva gives a BTL after 3 years, but most bochrim who go back to America to college will go to YU, Ner Yisroel, or Landers.
