Hi Krithika/Sunil,
Pls. tell me in detail when did u send the letter to the institute regarding termination means say after 1 mth of leave period or after completion of 3 mths leave because of your illness.
And after approval of termination when the re-registration can be done with the institute.
One of my friend is really in trouble. She is not well also and doctor suggested her to take rest for 4 mths.
