How to reject an accepted offer?

[fourier15]

Hello,

I have been offered an admit (with RA offer) from University X. The faculty wanted me to accept the offer as soon as possible. Hence, I accepted the offer on around 29th March. Here, acceptance means signed acceptance of RAship and also submitted intent to enroll in the university. Received the hard copy of I20 form at home address.

Now, I was ready to go for the University X. But with a surprise, I received an admit from University Y (much better than X) with full funding. Now, I am interested in moving to University Y. What steps should I follow now?

Questions:
1. How to deny the University X? How can I tell them to undo the intent to enroll form?
2. How to deny the Professor? What is the worse thing that can happen?
3. Will it be a problem if I have 2 I20 forms?

Thank you for the help.

I don't think i20 would be the problem. As long as you link your SEVIS number with the one from Y university. I'm not 100% sure about this, but according to my experience, this won't cause a problem.

I would take a second look at the intent to enroll form and see if there's a way out. You will lose your deposit (if there is one) but I think it should be OK to do that.

As for the professor, that depends. Some professors won't be offended by this, others will be.

1. That's up to you...I don't think there is a perfect answer for that, as you had already committed and the professor was counting on you. 
2. Well, the worse thing that it could happen is that the professor will be disappointed and probably angry...but that's all

3. That's not a problem, as long as you use the right one when you go for your visa and pay the SEVIS fees
