For the fall term application, I applied to 3 schools; one safety school and two schools I would rather want to attend. First I recieved the admisson from the safety school, with generous TA ship offer, and I didn't hear anything from the other two schools till 15th April, which was the deadline for the admission acceptance. Assuming I wouldn't get accepted to the other two schools, I accepted the offer from the safety school. Recently, However, I recieved an Email from a professor from one of the two schools, saying I will recieve the admisson. And yesterday, I recieved the official admission letter. Now I am wondering, if it is ever possible to withdraw my acceptance to the first safety school. Would it be possible? I am international student applying for grad schools in the US, so honestly, I don't know how the it might work out. Should I tell them honestly I got an admission from a different school and I would like to reverse my decision? I'll be very thankful for any opinions from you guys! Thank you very much guys in advance:) Hope you have a nice day.
