Articleship doubts... help!!!!!!

hey friends, i gave my ipcc both groups this past nov'13. Hopefully ill get d desired result. What i am really confused right now is if i register myself as a ca student and articleship trainee in delhi does it necessarily mean i have to do my articleship in delhi??? If not and i do my articleship elsewhere say kolkata, can i transfer back to delhi within the first year without much problem? (sorry for not mentioning here but i have my own reasons)
