I've got a fully funded PhD offer from a US university. The department is open to deferral without any reason.
I want to go to work for one year before my PhD. If I feel satisfied with the job, I may decline the PhD offer and stay in the industry. Is this common in the US?
My concern is (1) if I decide to drop out one year later, my advisor may not have enough time to admit new students. This may negatively impact her tenure. (2) My break of offer may cause the department doesn't consider students from my country/undergrad school.
