I am applying PhD for fall 2015 and I contacted several professors by email last year. Some of them told me that they planned to hire new PhD students and asked me to send my CV. But after I sent my CV to these professors, they never reply my emails. Now I have submitted the online application.
So my question is, during these days before the decision, can I drop by and visit professors during their office hours? If it is possible to make an appointment, email may not be a good method since many professors may ignore them. Will it be good to make phone calls to professors? I am an international student and I don't know much about whether making phone calls will be annoying to professors or not. Hope to hear your suggestions.
Many thanks
