Hey I am a international student, I received an interview invite from Columbia Neurobiology Program. Pleased I told my parents about it and they told many close relatives about it and I was getting their calls and best wishes. I also communicated with codirector who sent me the invite yesterday about problem in selecting interview date on Columbia webportal and visa process and she wrote to me back that they are working on it just five hours ago. Everything was normal. Until today's evening (five hours later) | received a email that the PhD invite mail was sent in an error and I will hear an update on my application next month from the university. I feel bad and anxious now. I know my parents will feel the same when I share this news with them. How should I interpret this error and should I ask more about this error. Did anyone else also received this email from Columbia Neurobiology and behaviour program. Any advice or experience would be helpful. This is my first time applying to PhD programs in US and haven't received any other acceptance or rejection email.
