Is there any time limit to Complete CA?

Hi Friends,

I have completed my CA Inter in Nov'1998 and had enrolled for Final. But due to employment i couldn't appear for final exams and now after a gap 10 years i am planning to Complete my CA. Kindly help me with following queries :

1. Is there any time limit fixed by ICAI to complete CA afer passing CA Inter?
2. How to re-validate the old registration?

I had sent a mail to SIRC but no reply from them yet.

Kindly advise.

Regards,
