Please help me make this sound natural Thank you very much for your time and information. However my visa still hasn't come through, I have bought a plane ticket. And I would arrive on 23 August. I like the idea of talking to you and learning about things before registering and I was searching to know if I could postpone the register for the fall term until I arrive there. I think this is the common way for PhD students over there, but I am not sure if it is okay by the department.
