May 1, the National Candidates Reply Date, is the deadline for formally notifying one college you will accept its offer of admission -- and sealing the deal with a check for the nonrefundable deposit. Keep in mind that you have signed a certification on your application form promising you will send a deposit to only one institution. Double- depositing— sending deposits to two or more schools in order to keep your options open— takes places away from other students. Your acceptance letter is conditional, and it’s easier than you think for the colleges to find out if you have deposited at more than one institution. If you ignore your ethical obligation and send deposits in to more than one school, you run the risk of both colleges rescinding your admission.
