@shankarneeda , Namaste ji.
You are asking about requirement of a form dictated by Indian Income Tax Code. We really cannot do justice to such enquiry --- the requirement / control of Foreign Exchange transfer in such cases is based on RBI and Indian IT. We generally deal with US taxes and currency controls . The information on form 15-CA/CB is at this site --> Form 15CA and form 15CB – Complete guide on filing| HDFC Life
Only thing I can tell you for certain is transfer of funds from / to a foreign source generally complies with your financial institutions own policy and US Treasury. Thus the bank will often raise a SAR ( Suspicious Activity Report ), even if the amount is under US$10,000 ( which is a general threshold ), --- it generally results in nothing ,.
Please consider consulting an Income Tax lawyer in India on this .
Is there more we can do for you ?
