hi cavit,
I am same as u. i was asked for the proof of unconditional letter of acceptance in mid may and sent it accordingly. As they didn't ask about other papers like health certificate and passport copy at that time (as it has been inscripted in application guideline accordingly) i emailed them whether they needed those papers at the same time or not. They informed that they didn't need these letter at that time. So, i think, they will ask these papers after the final result.
..now just waiting for final result. can u tell when can it be come out??
