then you should wait. YOu applied on 15th March and till date, it's been only 6 working days. Hence, it's normal time they take to process. You should hear a good news in another 3 to 4 working days and do not forget 27th and 29th, both days are off for all CHCs in India followed by saturday and sunday. Hence, you should hear from them either on 28th or 1st april.
Cheers!
