@skieurope you’re right - things have changed and that’s why I think a student of that caliber would have known better or have been coached by Harvard. My son volunteered for a semester tutoring exchange students. His student was a grad student from an interesting country so I asked if he planned on keeping in touch. He said that his university prohibited exchanging numbers with their students, who may or may not have legal status. If his student got interviewed by ICE or something they did not want my sons contact info on his exchange students phone to get swept up in the mess. If the info was provided by Harvard and student ignored it maybe he lost his shot at attending school here.
