Hello Amit,
It is clearly written in guidance note of icai that request for change of examination centre will not be entertained. Read full para carefully:
3. EXAMINATION CENTRE : You have to select examination centre from amongst the centres as indicated in the attached list from where you wish to appear in the ensuing examination. The examination centre varies from examination to examination. Please be careful and be doubly sure before you write the centre as no request for change of centre will be entertained subsequently under any circumstances.
Thanking You
