在美国申请undergraduate,拿到奖学金,但一时走不了

It depends on whether your university has that service.

Princeton does. IT allows its admiited students to extend enrolment up to one year, and still keep their scholarship..

But for your case, it really depends on your school.

ASK them, even if they do not have that policy, just explain to them what your difficulty is and why you can not go .

If you reasons are good and they are nice and want you, chances are that you could do it.

May you be mindful and be liberated from worries.
