Hi everyone,

I had an interview for a PhD position at a UK University in March end, and received an email from my interviewer, and potential supervisor a week later that I have been offered the position, and I need to accept it. Once I accepted it, I got a mail saying I will get the official offer letter later, which can take upto a month. It's been 15 days, and I haven't got the official offer yet. Is there a possibility that they might not offer me the position, as in not send the offical offer letter? Since, I am an international candidate, latest by which date should I expect the official offer, as I need to have some time for visa applications, etc.? Also, should I start worrying, as it's Easter time, and I don't know, if offers are sent out this late in April?

Thanks a lot, in advance!
